}}

==Explanation==

This comic documents another of [[Beret Guy]]'s [[:Category:Strange powers of Beret Guy|absurdist ventures]]. He explains to [[Megan]] that "we" (possibly [[:Category:Beret Guy's Business|his company]]) are testing their new "retractable" rocket.

{{w|Reusable launch system|Reusable rockets}} are a growing industry, as they are more economically viable in the long run – though technically much more difficult to operate – than rocket boosters that are just discarded after use (which have been standard throughout the majority of space-faring history). Thus, Megan is understandably confused about Beret Guy's assertion that theirs is "retractable", asking if he misspoke. In typical fashion, he assures her that he did not misspeak, with a single "No" without further explanation.

They proceed to watch the rocket "launch", proving that it is indeed ''retractable''. In fact the rocket does not launch, but merely ''extends'' – apparently all the way to the {{w|International Space Station}} (ISS), a height of over 400 km (over 250 miles) – before retracting, as promised, to its original position. The top part, with the astronauts in it, has been left in space. Presumably, it is docked to the ISS, as the crew onboard the ISS say hello to them in panel 4.

Of course, it would not be possible to extend anything this far.{{Citation needed}} The top would need to be moving very fast compared to the bottom part, or it would bend westwards and break, and even with the strongest material a fully extended, very thin, presumably, hollow structure with a payload on top would {{w|buckling|buckle}} very soon after extension began. Also, the ISS moves at 27,600 km/h (17,100 mph) compared to the ground under it, making an orbit in about one and a half hours. So making the tip follow this long enough to dock would be even more impossible.

A possibility of making a {{w|space elevator}} has been discussed, but it would not extend like this with a payload on top. Randall has, for instance, referenced space elevators in [[697: Tensile vs. Shear Strength]]. He has also examined the problems of a solid metal object extending through the atmosphere [https://what-if.xkcd.com/157/ in a what-if].

The current method of sending rockets into space requires huge amounts of fuel, and the more fuel you attempt to carry, the heavier the rocket, leading to more fuel being required, etc. ({{w|Tsiolkovsky rocket equation}}), which makes the current method inefficient. Alternate methods are being explored, such as using a slingshot (such as {{w|SpinLaunch}} which had their a successful test flight of a smaller scale launcher just days before this comic was published and probably the influence for this comic), theoretical {{w|space elevators}}, or this comic's impossible retractable rocket idea, all of which would leave the majority of the "fuel" requirements on Earth or elsewhere rather than having to carry heavy fuel with the rocket. The only fuel carried might be minimal amounts for course adjustments once in space rather than large amounts used to get there. However, many of these methods are less flexible than rockets; the space elevator, for instance, operates on the basis of constant angular velocity relative to the Earth's axis of rotation, meaning that it cannot launch payloads directly into low-earth orbit, polar orbits, or many other orbits frequently used by satellites for their desirable characteristics, and satellites intended for these orbits might still need to carry considerable amounts of fuel, even if less than that required to launch directly from the ground.

The title text parodies the 'old' single-use boosters. It appears that the predecessors to the 'retractable rockets' were capable of controlled extension only. Once they had lofted the payload to orbit, they were then allowed to fall over, destroying them in the process so they could not be used again just like booster rockets. However, if a 250 mile/400 km high construction just fell over, it would be much more difficult to avoid other damage, than to the rocket (booster), than for just a few small booster rockets falling out of the sky.{{Citation needed}}

This comic was released four days before (and possibly refers to) SpaceX's {{w|SpaceX Crew-3|Crew-3 mission}} to send astronauts to ISS with a reusable rocket on 31 October 2021.

2537: Painbow Award

2021-11-04T04:19:07Z

108.162.250.114: /* Explanation */ add note about sharp transition

{{comic
| number = 2537
| date = November 3, 2021
| title = Painbow Award
| image = painbow_award.png
| titletext = This year, our team took home the dark blue ribbon, better than the midnight blue we got last year but still short of the winning navy blue.
}}

==Explanation==
{{incomplete|Created by MELLLVAR - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic makes fun of the sometimes-displeasing color gradients used in the figures for scientific papers by suggesting that the scientists picking them are in competition to use the least-pleasing gradient. The title of the comic is a portmanteau of "pain" and "rainbow" suggesting a humorous name for terrible gradients.

The gradient here showcases a collection of unintuitive and unhelpful decisions. Starting from the top, white fades down into green, which then fades into red (passing through brown in the middle instead of yellow, indicating {{w|subtractive color}} mixing instead of {{w|additive color}} mixing, for no obvious reason). The red then turns ''back'' into green as the intensity increases further. Red and green in close proximity make the power levels hard or impossible to distinguish for those with {{w|Color_blindness#Protanopia|protanopic colorblindness}}. This confusion is repeated at lower power levels, where blue transitions to black and then back again, before finally transitioning back into white. The highest and lowest recorded power levels have the same color value, which is less than ideal.

Although it's possible (for someone with full color vision) to interpret data from this graph from context clues - the white that fades to green is high-energy white, while the white that fades to blue is low-energy white - there's no benefit to doing things this way, and a lot of downsides. Additionally, there are regions in the color scale where the color changes very rapidly, which creates the false appearance of an edge in what is likely a smooth function.

Real-world analogues to the Painbow Award include radar meteorology charts, where different types of precipitation have different color schemes that can overlap and blend in confusing transition zones.

The title text takes the concept of bad color combinations further, suggesting the use of navy blue, dark blue, and midnight blue for first, second, and third respectively, even though most people would perceive these as being the same or very similar colors. However, the choice of blue(s) may be a direct play upon the association of the {{w|Blue Riband}} (a.k.a. "Blue Ribbon") and/or {{w|Le Cordon Bleu|Cordon Bleu}} (likewise, but this time direct from the French) awards, extended in common use for excellence across a much wider range of competitive fields.

For rosette-rewarded competitions (e.g. livestock parades, dog-shows, etc) the first prize ones are commonly blue (red and yellow for 2nd and 3rd, respectively), though it may not be logically obvious to someone unfamiliar with this, perhaps more used to yellow depicting the 'gold standard, first place' indicator or red as the most alerting hue in some other ranking situations. Where a depicted award schema ''is'' directly gold/silver/bronze-influenced, however, the gold and bronze 'metallic off-yellows' can sometimes be more confused with each other than with the mid-level desaturated 'silver'

* When originally uploaded, the caption used the phrase "color gradient" rather than "color scale"

:[A graph named 'Figure 2' with two axes is shown. The vertical axis is labeled 'λ' and the horizontal axis is labeled 'θ (phase)'. On the right side, a bar labeled 'Peak Energy' is shown, with colors starting from black, to green, to red, to green, to yellow, and to white from bottom to top. The center of the graph is a messy shape with ugly gradients from these colors.]

Talk:what if?

2016-07-01T10:12:04Z

108.162.250.114: /* No more what ifs */

[[Special:Contributions/108.233.66.118|108.233.66.118]] 21:11, 16 April 2013 (UTC)so is anybody weirded out by last week's post on the worst thing pressure cookers can do, followed by yesterday's terror attacks using pressure cookers?[[Special:Contributions/108.233.66.118|108.233.66.118]] 21:11, 16 April 2013 (UTC)
Do you want me to remove the articles not in the book, or label the ones IN the book? [[User:MadHaighaHatta|Completely sane (And not Anglo-Saxon)]] ([[User talk:MadHaighaHatta|talk]]) 11:34, 5 August 2015 (UTC)
Do we want to add some references to the different What-If articles? Obviously putting up an explanation would be a bit of a waste since Randall goes into a lot of detail himself on any given subject. Some good things to mention might be the title-text on each image, mentions of recurring themes, and maybe some thought about the original subject mentioned (such as the "Space Oddity" music video that was the subject of a recent article). [[Special:Contributions/76.106.251.87|76.106.251.87]] 17:11, 30 May 2013 (UTC)

:"What if" is not {{w|Creative Commons}} related, so respect Randall's copyright. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 18:05, 30 May 2013 (UTC)
::Sorry. Didn't realize that reviewing a creative work fell into copyright issues. No disrespect intended, only ignorance. [[Special:Contributions/76.106.251.87|76.106.251.87]] 19:16, 30 May 2013 (UTC)

:I agree that "what if?" is not ''clearly'' under CC-BY-NC-2.5, but the link next to the Copyright goes to xkcd itself, which clearly does say it is. [[User:Markhurd|Mark Hurd]] ([[User talk:Markhurd|talk]]) 13:40, 12 August 2013 (UTC)

::Agreed. What-if appears to fall under the general xkcd copyright- it says "Copyright ©2012-13 xkcd." with the link pointing to general xkcd copyright info. "http://xkcd.com/license.html" also says that "you are free to copy and reuse any of my drawings (noncommercially) as long as you tell people where they're from." which includes what-if drawings, and I'm not sure if just part of a work could be copyrighted without Randall explicitly saying so. I also think it would be a good idea to have articles on the what-ifs for more information not stated in the what-if itself. {{unsigned ip|109.144.146.171}}

:IANAL, so I will leave the copyright issues unaddressed as I respond to the original question in the affirmative: yes, we should have a page for each What-if article. [[Special:Contributions/173.245.55.63|173.245.55.63]] 15:54, 14 April 2014 (UTC)

== Logo/Header ==

I'm convinced there is some sort of specific joke in the "What If" logo, but I'm failing to grasp it.
Knowing Randall, there has to be something funny about using a crane to lower a T-rex into the Sarlacc. [[Special:Contributions/173.245.49.90|173.245.49.90]] 11:53, 3 February 2014 (UTC)

[http://www.nerdist.com/2014/08/exclusive-heres-your-first-look-at-xkcds-what-if/ Nerdist Review] says "Remove the jacket, and you can see how that particular experiment worked out in Munroe’s mind" {{unsigned ip|199.27.128.118}}

== Discussion regarding [http://what-if.xkcd.com/91/ What-if 91] ==

I believe that Randall missed an opportunity to discuss means of harnessing thermal energy. See, original question specified HOT water!
:He has to pay the electric bill. He couldn't make back the energy spent to heat the water due to entropy. [[Special:Contributions/108.162.237.161|108.162.237.161]] 05:51, 31 July 2014 (UTC)
Shall we forgive him this oversight and carry out some analysis to determine the harness-able energy content of hot water from the bathtub faucet in an average American apartment building?

:TODO: discuss Sterling engines or other strategies here. (That means you! :) )

:I believe that even when you "run out of hot water", the incoming water will still have energy added since the gas or electric water heater will be running non-stop, turning cold water into slightly-less-cold water. Since slightly-less-cold water is still colder than the ambient temperature in the apartment, I'm not sure how to harness the energy added by the water heater... But neither am I sure that "you can't". TODO: Can someone confirm that you can't?

Shall we then turn the dial up a notch, [http://what-if.xkcd.com/35/ What-if 35 style], and imagine how the scenario changes if the apartment building has a water heater that is perfectly capable of keeping the hot faucet piping hot, even if you run it 24/7?

: Suppose the super water heater turns 15C input water (cold) into 50C output water (hot). I think that means that the water heater adds 35 calories (not kilocalories) of energy per milliliter. I played with this expression in Google Calculator "(35/1000) calories per ml * 1 liter / 1 second" and determined that 1. Google uses kilocalories for "calories", thus the /1000 part... and 2. it takes ~150 watts to turn a liter of cold water into a liter of hot water in *one second*.

: Let's stop this for now and see if anyone is interested in participating. [[Special:Contributions/173.245.55.63|173.245.55.63]] 16:28, 14 April 2014 (UTC)

::Go here: [http://fora.xkcd.com/viewforum.php?f=60 What If? discussion]. That's a BIG forum to discuss your items. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 23:16, 14 April 2014 (UTC)

== Discussion area ==

Is there a discussion area for each of the "what-if?" pages? - Eg I'd like to point out that in #111 "All the money", the mouse-over text in the tombstone graphic says "Cash Ruled Everything Around Me" - or C.R.E.A.M. - coincidence? ;) Also, there have been past pages in which there have been items which I would contest some facts/statements, or seek further explanation. [[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 13:06, 4 September 2014 (UTC)

I would love to see an analysis of the most recent "what-if" - [http://what-if.xkcd.com/120/ What-if #120] as I'm sure each excerpt from an alternate-universe "What-if" column has an interesting background. Surely even if the article isn't Creative Commons some discussion of it is legal. Yes, I see that there is a thread on the forum for discussing this what-if but it is not succinct. [[User:Momerath|Momerath]] ([[User talk:Momerath|talk]]) 05:56, 3 December 2014 (UTC)

Is there a way this could auto-update like the regular part of the Wiki does? (I assume it auto-updates). This entry will never close if we don't do that and other than listing them and linking to them, there is nothing to say. [[User:4jonah|4jonah]] ([[User talk:4jonah|talk]]) 19:29, 1 May 2015 (UTC)

As Randal stated, He will return posting his "What If?" on Tuesday, July 14th 2015, at 07:49:59 EDT.
I have attached countdown below, to verify it.

== List of articles ==

I don't have time to do much editing right now, so could someone else go and put the list of articles into a table to make more use of the page's width? Perhaps split it into groups of 20-40 entries in a cell, aligned left-right in chronological order and prefix each entry with the article number. Just an idea. [[User:Pixali|Pixali]] ([[User talk:Pixali|talk]]|[[Special:Contributions/Pixali|contribs]]) 00:32, 21 May 2015 (UTC)

== Why isn't there an explanation page for each what if? ==

I love the What If? series, and consider it to be a similar, yet separate, version of the normal comics. There are many things that, while reading the What If?, I was confused, interested, or amused by, and I wanted to read about it on this wiki. Randall puts much effort into these, as well as the normal series, so they deserve some explaining. I have no idea how I'd go about this on my own, and I don't have the time right now to spare. I merely want to (hopefully) get the ball rolling on this, if it isn't already. {{unsigned ip|108.162.221.145}}

== The UK Version of the book. ==

I've edited in the UK version's summary, as I own the book. I will write about the date of the UK book's release too and the foreword. Is there anything else about it that other users think should be added?

== Can we explain this? ==

Can we explain the questions there, or not? [[Special:Contributions/108.162.218.77|108.162.218.77]] 23:09, 3 October 2015 (UTC)

== No more what ifs ==

Should we include a note that Randall seems to have stopped creating What Ifs? The last one was over a month ago [[User:Mikemk|Mikemk]] ([[User talk:Mikemk|talk]]) 07:55, 27 October 2015 (UTC)

He might be working on his book ''Thing Explainer''. Xkcd last posted 2 days ago. [[Special:Contributions/108.162.218.77|108.162.218.77]] 22:49, 15 November 2015 (UTC)

I think that we should conclude that this site is over if there isn't another post by New Years. [[User:Bbruzzo|Bbruzzo]] ([[User talk:Bbruzzo|talk]]) 19:23, 5 December 2015 (UTC)

I think we should just say it's over now. There hasn't been a post in months and ''Thing Explainer'' has been out for quite a while now. [[Special:Contributions/108.162.237.87|108.162.237.87]] 19:10, 12 December 2015 (UTC)

Nope! There is a NEW xkcd what-if today, [http://what-if.xkcd.com/141 Sunbeam]! All may rejoice! [[User:AJMansfield|AJMansfield]] ([[User talk:AJMansfield|talk]]) 16:23, 12 January 2016 (UTC)

==Explanation==
{{incomplete|Fill out the [[#Items in the garden|tables]] with images of all the possible items. General explanations/comment are missing as well as link to screenshots of gardens where each item "grows".}}

This comics represents the [[:Category:April fools' comics|April fools' comic]] of 2016, and it is [[Randall|Randall's]] celebration of {{w|April Fools' Day}} Friday, April 1, 2016. It represents the third time in a row that user input changes the April Fool's comic. Although in the last two [[1350: Lorenz]] and [[1506: xkcloud]] it was written (or drawn) input that became part of the comics. This time the user input is like a game, as the user actively adds, moves and deletes items, and new items appear based on these actions. In this way it actually more resembles the game comic [[1608: Hoverboard]], than the previous April Fool's comics.

Due to technical problems (or to make fools of his fans (see more about the [[#April Fool's header text|header text]] below)) the comic did not go live until Sunday evening (after midnight, so technically first on Monday April 4th) so there was no Friday release the week before, see [[#Monday 4th of April release|more details below]].

The comic begins with a [http://www.explainxkcd.com/wiki/images/f/f1/Garden_Loading_collage.png loading screen] with a revolving tree and the text "loading..." This is because the first time a computer loads this dynamic comic it can take a while.

Once it is loaded it displays "your '''Garden'''" being the barren landscape, with a small pond to the left, some rubbles far left and right and a single lamp shining light yellow light on most of the ground. This is what is shown at the top of the explanation here. But if you leave the lights on and wait (or "relax", as the reader is told to do by the title text), then plants and other items will start to appear.

The reason it is correct to call it "your garden" is that every time this comic is loaded from scratch, a new garden will be created with a unique url-address. By [[#Saving garden with url|saving this link]] (making a bookmark for it), the user will be able to return to their garden again and again. As the garden only develops very slowly this is important. (If users wish to share their garden they can do it in the table on the page for '''[[1663: Garden/Users gardens|Users gardens]]''').

[http://www.explainxkcd.com/wiki/images/7/78/1663_garden_Three_colors_over_everything_not_very_interesting.png Plants appear] one at a time, and sometimes it takes a long time. Only a few of the plants actually grow. For instance there are some large trees that begins as [http://www.explainxkcd.com/wiki/images/2/27/1663_garden_Fast_growing_tree_-_leafless.png a large trunk] and from there [http://www.explainxkcd.com/wiki/images/6/67/1663_garden_Fast_growing_tree_-_lots_of_leaves.png grows branches and leaves]. This can sometimes happen quite fast. Most other plants just appear, the only other exception being one type of flowers. All plants, except cactus, clearly sway in the breeze.

Also [http://www.explainxkcd.com/wiki/images/5/5a/1663_garden_Pruned_garden_with_birds_deer_gate_cactus_turtles_snake_gate.png animals] and [http://www.explainxkcd.com/wiki/images/d/de/1663_garden_Three_lamps_two_along_ground_with_pillars_not_in_blue_world_and_symmetric_gates.png building like structures] like [http://www.explainxkcd.com/wiki/images/1/15/1663_garden_Megan_Monolith_Animals_and_more.png a Monolith and birdbaths] appear together with lots of other items like [http://www.explainxkcd.com/wiki/images/a/ad/1663_garden_Office_space_with_star_plant_balloon_with_bird_and_grass_on_Cueball.png office furniture] with [http://xkcd.com/1663/#98dc3452-fcf2-11e5-8010-42010a8e0008 balloons swaying in the wind] or even one of the [http://www.explainxkcd.com/wiki/images/3/3f/1663_garden_One_color_Between_orange_red_and_red_First_thing_Mars_rover.png Mars rovers] which so [[:Category:Mars rovers|often has been featured]] in xkcd.

On top of all this there several known characters may appear in different poses including [[Cueball]] and [[Megan]] (for instance with a sword, see [http://www.explainxkcd.com/wiki/images/6/6b/1663_garden_Megan_with_sword%2C_trees_octopuses_with_Cueball_bunny_ducklings.png here]), [[Ponytail]] (see [http://www.explainxkcd.com/wiki/images/e/eb/1663_garden_Ponytail_and_two_Cueballs_cat_pillar_and_trunk_sE.png here]) and [[Beret Guy]] from the torso and up (see [http://www.explainxkcd.com/wiki/images/9/9b/1663_garden_Three_colors_more_separate_Beret_Guy_in_shrubbery_and_Octopus_on_office_desk.png here]). Megan and also Cueball can both be seen [http://www.explainxkcd.com/wiki/images/0/06/1663_garden_Giant_planter_on_pillars_and_both_Cueball_and_Megan_with_black_hat.png with a black hat], but it is one that "grows" on top of their heads after they first appear. However, Cueball with a black hat automatically turns into [[Black Hat]], so he can also be said to be in this comic. There is also an unknown character, a [http://www.explainxkcd.com/wiki/images/0/0c/1663_garden_One_color_Between_Light_yellow_and_yellow_First_thing_stilts.png girl on stilts] with black hair in a ponytail who like plants and balloons [http://xkcd.com/1663/#e774b4b8-fcd4-11e5-8001-42010a8e0017 sways in the wind].

All the [[#Items in the garden|items that can appear]] in the garden are listed below in several tables. During the first week new items kept appearing, but after the eight day (April 12th), no new items seems to have appeared. Also the growth rate (and thus the fun of this comic) has decreased with time (maybe due to the enormous amount of gardens that the server has to keep track of?)

Every so often the image will refresh. You can change the number of lamps, their position, direction, beam width and the color temperature which always begins somewhere between white and yellow, but can change all the way from red to blue (See this [http://www.explainxkcd.com/wiki/images/b/b8/Garden_Three_Lamp_screen_shot.png example] with one lamp selected and three colors of light). Other colors than those four may appear where two lamps light cone of different colored light overlap.

The color of light [[#Effect of light|effects the growth]] with a strong correlation for what appears in the garden depending on the [[#Colors of light|color of light]], and this is not only split between red, yellow and blue, but rather in more than [http://www.explainxkcd.com/wiki/images/4/4a/1663_garden_Numbered_color_scale_1-17.png 10 different colors].

Early on it became clear that pure red light results in a desert theme with [http://www.explainxkcd.com/wiki/images/9/98/1663_garden_Desert_with_red_light_only.png cactus and turtles] and pure blue light gives an aquatic theme with [http://www.explainxkcd.com/wiki/images/2/23/1663_garden_Octopus_garden_with_Cueball_hand_up_and_a_black_hat_octopus.png lots of octopuses] that may also wear the black hat! For the most interesting gardens the [http://www.explainxkcd.com/wiki/images/1/15/1663_garden_Megan_Monolith_Animals_and_more.png light colors should be mixed], see more below under [[#Effect of light|Effect of light]].

If this comic is scientifically accurate, that correlation will be based on {{w|photosynthetically active radiation}}.

Some users manage to create fantastic gardens (by using lots of time on them, pruning them at the right time and changing the light and lamp position to get what they strive for). Especially one user have created a series of amazing gardens that is posted on another [http://forums.xkcd.com/viewtopic.php?f=7&t=114415&start=600 xkcd forum]. Here is a collection of screen shots with some of [[1663:_Garden/Screen-shots#Blitz_Girls_amazing_gardens|Blitz Girls amazing gardens]]!

The title text "Relax" can be debated. Is it to let the users know they should just sit back and relax as the garden grows. Or should they relax and don't worry so much about how it works (not working here on explain xkcd though!) Or is he teasing the users by giving them a garden that they need to tend to, and then telling them to relax. And also giving them many more colors than lamps... Given that this comic was supposed to come out on April 1st, there is a good chance that it is, also, to tease the users. There are actually [[#Trivia|two other title texts]] as well.

===Extra Garden pages===
*Since this comic is so complicated extra pages have been created to include much more information than is wished for on this main page (which is already of considerable size).
*These pages are listed here for convenience, but they are also linked in the relevant sections below:
**[[1663: Garden/Images]]. The images of items that can appear in the comic.
***This page is linked in the section below with table for ''[[#Items in the garden|Items in the garden]]''.
**[[1663: Garden/Screen-shots]]. Since there are no permalink it in order to save a particular moment of a garden a screen shot is needed. These can be posted here.
***This page is linked in the section below about for ''[[#Saving images|Saving images]]''.
**[[1663: Garden/Users gardens]]. A place for users of explain xkcd to post links to their own garden, and also for experimental gardens.!

==Transcript==
:[After a '''loading image''' with a rotating tree in the middle and the text "Loading..." with the three dots appearing one at a time, and then disappear when all three have been there the image shown above in the explanation will appear:]

:['''Description of the image above''': A piece of bare landscape is shown. At the edges there are some rocks or stones raising the level from the general level through the center of the panel. Above the middle, a little more than halfway to the to of the panel, is a light bulb sitting inside a lamp that reminds of the desk lamp from the movie Luxo Jr. The lamp shines a yellow light down on the landscape in a broad cone that jus reaches the first rock to the left, but not those to the right. The lamp just hovers in the air. In the top right corner are two gray icons. The top one has a black frame and shows an image of a lamp, tilted left as opposed to the straight position of the lamp in the image. There is a + sign below in the left corner. The second icon without a frame has a large white cross in the middle.]

:[This turns out to be a '''web applet''' and using the "+ lamp" icon two more lamps can be added getting up to three. They are all adjustable both regarding position, direction, color of light and beam width. When selecting a lamp a red circle appear around it with a small circle on top that can be used to control the light color from blue to the left to red to the right. In front is a red arrow that can turn the lamp and it can also be used to change the beam width by pulling it away from the lamp or pushing it back. The lamps can be moved by just clicking on it and moving it. The other icon with a X can be used to remove the lamps (and later any object that appear in the garden). When any object is selected there is a red circle around it. When this is done the gray cross icon becomes red and can the be used to delete the selected item. When no item is selected (either because it is deleted, or by clicking in a part of the screen with no items), then the cross icon turns gray again. When all three lamps are on, then the "+ lamp" icon is faded out.]

:['''If you wait''' (or relax, as in the title text), then a plant will grow or animals, humans and other items may appear. This could be birds, snakes, octopuses or turtles, Megan or Cueball or a birdbath, a monolith or a tall gate just as a few examples. Most of the items appear in one go, but at least the largest trees grow up with a big stem first and then adds parts later with leaves or empty branches. Also one item may appear on top of another item and for instance birds may fly in the air.]

==Functionality==
===Saving garden with url===
*There is no [[1350#Permalink|permalink button]] as in the last two years' April Fool's comics.
*The URL is different for every garden that is loaded, but stays the same. It links to a server-side copy of the scene, which then changes depending on what the users does with their gardens.
**Sharing a URL will connect a new browser to the same garden session, but only the original browser will be allowed to edit.
**The user can always return to change the garden with the link, but only from the same browser on the same computer.
**This means that a specific moment in a gardens life has to be [[#Saving images|saved as an image]] for future references.
*The garden itself will thus continue to develop further from the time when the url was copied, and events will happen from now on even though the garden is not opened in any browser.
**If the user doesn't keep it, it will become infested with weeds.
**So most likely the garden is serverside, as all browsers are allowed to see the development of this garden, but users following the url are not allowed to edit anything.
*Here is an example garden [http://www.xkcd.com/1663/#0d11a2c8-fa8f-11e5-8001-42010a8e000e linked by ID] versus the same garden:
**In the original [http://www.explainxkcd.com/wiki/images/7/7f/1663_garden_tree_turtle_birdbath.png screenshot from April 4th] from when the url was created
**In a [http://www.explainxkcd.com/wiki/images/7/7c/1663_garden_Flying_birds_deer_gate_with_cactus_turtles_snake_etc.png screenshot from April 5th] the day after.
**Here [http://www.explainxkcd.com/wiki/images/5/5a/1663_garden_Pruned_garden_with_birds_deer_gate_cactus_turtles_snake_gate.png example] after the user pruned the garden in the examples.
**Other [[1663: Garden/Users gardens|user gardens]] can be found on the link.
*Starting two browser windows or tabs pointing to the same URL will allow you to edit from either window.
**linden.xkcd.com holds all the data; the UUID just corresponds to your access key, held in your browser's local storage.

====Saving images====
*Since the [[#Saving garden with url|urls are changing]] the only way to save a particular garden is to save an image of the current garden.
**Alternatively by deleting all lamps (or changing them to laser beams or turning them upwards) the no new growth will occur. But then the garden will no longer develop.
*In Edge, Firefox and Chrome, the image plus light cones but minus lamps and icons elements, can be saved by right clicking in the image. (Not possible in explorer).
**They do not always save in the same way as some browsers saves the part of the background without any light cones as white, and other save it as no background, in which case it may render black, basically hiding any black items outside the light.
***For those images it depends on which viewer is used to see the image, if everything can be seen or only that in the light cones.
****See examples of how it looks with black background in these two color maps collections using [http://www.explainxkcd.com/wiki/images/5/50/1663_garden_Single_colors.png a single lamp] and [http://www.explainxkcd.com/wiki/images/9/90/1663_garden_Three_colors.png three lamps].
****See more details about how these [[1663:_Garden/Screen-shots#Color_maps|color maps]] have been made.
****See also (at least) two examples of saved images as the are here on explain xkcd [[1663:_Garden/Screen-shots#Saved_image_from_xkcd|here]].
*An image of the whole screen can be captured, by pressing the PrtScn (Print Screen) key on the keyboard & then pasting the content into a blank image in an image-editing program.
**An even better solution is to use a tool like {{w|Snipping Tool}} which can take the part of the screen that are relevant. This is how most of the [[1663: Garden/Screen-shots|screen shots]] for this explanation has been aquired.
**In both way the lamps and icons can also be displayed, which is not an option with saved images.

===Lamps===
*Additional lamps, up to a total of three lamps, can be added by clicking the black plus lamp icon along the right of the window. The control will black plus lamp icon will [http://www.explainxkcd.com/wiki/images/b/b8/Garden_Three_Lamp_screen_shot.png turn gray].
*Lamps can be removed by clicking to select a lamp, then clicking the red X icon along the right of the window, or pressing the Delete or Backspace key on the keyboard. All lights can be deleted.
*The position of the lamp can be moved by clicking and dragging the lamp within the scene.
*The angle and area of the light cone emitted by the lamp can be changed by [http://www.explainxkcd.com/wiki/images/0/09/Garden_Red_Lamp_screen_shot.png clicking to select the lamp and to reveal the red control triangle]. Rotating the control triangle around the lamp will change the aim of the lamp to point in the direction of the triangle, dragging the control triangle towards the lamp will [http://www.explainxkcd.com/wiki/images/c/cc/1663_garden_One_color_Light_blue.png widen the beam], and dragging the control triangle towards away from the lamp will [http://www.explainxkcd.com/wiki/images/5/5a/1663_garden_Pruned_garden_with_birds_deer_gate_cactus_turtles_snake_gate.png narrow the beam].
*The color emitted by the lamp can be changed by clicking the lamp to reveal the colored control dot, and by rotating the dot around the lamp. The small color control circle changes color to match the color of the lamps beam of light. new lights default to a center position, emitting a pale green. '''rotating the control right''' changes the color to yellow, orange, and finally red, and '''rotating the control left''' changes the color to white, then blue.
===Colors of light===
*The color control moves in a smooth gradient between colors, along the spectrum without any set positions.
*Small changes in the color can have an effect on the garden, even though there is no clear change in the color.
*[http://www.explainxkcd.com/wiki/images/5/50/1663_garden_Single_colors.png As many as nine colors] can be identified from the emitted light of a single lamp, and many more colors are evident when [http://www.explainxkcd.com/wiki/images/9/90/1663_garden_Three_colors.png two or three lamps overlap].
*There is reason to believe that even half the change will create different gardens, i.e. there can be at least one more position between those nine settings that will change the effect, giving eight more settings for a total of 17 "different" colors. An experiment with such '''17 settings''' for just [[1663:_Garden/Screen-shots#One_lamp_one_color|One lamp with one color]].
*Several unique elements only seem to appear using the eight half-colors. Both the [http://www.explainxkcd.com/wiki/images/3/3f/1663_garden_One_color_Between_orange_red_and_red_First_thing_Mars_rover.png Mars rover] and the [http://www.explainxkcd.com/wiki/images/1/1b/1663_garden_One_color_Between_Light_yellow_and_yellow_First_thing_stilts_right.png Stilts girl] might be missed.
*Colors can thus be indicated from these 17 divisions: 
**Below is a table with these 17 division shown and what to expect.
**This may change over time, but was as it about a week after release.
***If updating, please make a note that this may have only applied during the first week(s) and add new feature without deleting.
**There has been an [[1663:_Garden/Screen-shots#One_lamp_one_color|experiment made]] with these 17 colors, see that for more details.
***The color names links to these experimental gardens, that will never be changed after the initiation.
***But there are reasons to believe that two gardens made identical may develop quite differently, as it seems some gardens have very limited growth in spite of the same light. Some of these gardens may be of that persuasion.
****This was proven when 34 more gardens using the 17 colors where started in a [[1663:_Garden/Screen-shots#Second_experiment|similar experiment]].
*The debugger reveals that each light has a "temp" property which ranges from 0 (red) to 1 (blue). The default setting is 0.5.
**The RGB color corresponding to "temp" is determined by this function in linden.js:
::<tt>function u(t){return.32>t?[1,.5+.5*t/.32,.5]:.64>t?[1,1,.5+.5*(t-.32)/.32]:[.75+.25*(1-t)/.36,.75+.25*(1-t)/.36,1]}</tt>

===Effect of light===
*How much the color affects the growth took some time to find out but already from the stat it was clear that there definitely was a correlation
*For instance areas under lights set to the the outer position or the starting position was very different.
**[http://www.explainxkcd.com/wiki/images/2/23/1663_garden_Octopus_garden_with_Cueball_hand_up_and_a_black_hat_octopus.png Pure blue light] (left most) develop into a boring aquatic theme with only lots of octopuses (maybe with a black hat) and the Cueball holding a hand out to check for rain.
***The appearance of pure blue gardens have changed with time so octopuses now only appear over the pond [http://www.explainxkcd.com/wiki/images/1/1d/1663_garden_One_color_Blue_9d.png like this].
**[http://www.explainxkcd.com/wiki/images/7/70/1663_garden_One_color_red_9d.png Pure red light] (far right) develop into a boring desert theme with only cactus and turtles.
**[http://www.explainxkcd.com/wiki/images/9/9c/1663_garden_One_color_Light_yellow_9d.png Light yellow] or [http://www.explainxkcd.com/wiki/images/2/2e/1663_garden_Color_09_3d.png starting light] grows lots of plants like trees, grass and scrubs and several animals like ducks, deer, fish and wadding bird and also birdbath, stilt girl and both standing Megan and sword Megan.
*Soon after the release of the comic some research into a single lamp with unchaining light, that covering the whole light range split into 17 divisions was undertaken.
*[[File:1663 garden Numbered color scale 1-17.png]]
**See these gardens [[1663:_Garden/Users_gardens#Locked_gardens_only_for_explanation_use|locked for explanation use only]] and also see more about the 17 split in the color range [[#Colors of light|above]].
*Mixed light seems to be able to do the same, but it is unclear if what grows only depends on the final mixed color, or if it is a mix of what would grow under those two colors.
**There are some indications that it is not a clear mix as pure blue together with pure red, does not seem to produce neither Octopuses or desert theme.
**If there are any items that can only grow under a mix of light this has not been proven. Most objects that can grow directly from the ground, has been observed in the experimental single color gardens mentioned above.
**But there may be items that needs to grow on top of other objects, and these may require a change of color from what the base needs. And thus they will not appear under one color light. Possible examples of these items could be:

*What happens when using only one color (other than the two outer points red and blue and the starting light yellow color) has been explored in great depth in no less than two different [[1663:_Garden/Screen-shots#One_lamp_one_color|One lamp one color]] experiments with [[1663:_Garden/Users_gardens#Locked_gardens_only_for_explanation_use|51 gardens]] created using 17 different color settings.
**[http://www.explainxkcd.com/wiki/images/2/27/1663_garden_One_color_Between_blue_and_light_blue_6d.png Blue light] (just right of pure blue) creates a landscape with stones forming cairns, together with monoliths, both kinds of Cueballs (with black hat on the standing one) and still octopuses.
**[http://www.explainxkcd.com/wiki/images/7/75/1663_garden_One_color_Light_blue_9d.png Light blue light] (just a little farther from pure blue than above), the octopuses disappear, but the rest remains the same, although boats and wadding bird now appear in the water, and still both [http://www.explainxkcd.com/wiki/images/a/a6/1663_garden_Color_03_5d.png Cueballs] can occur. Going just slightly further away [http://www.explainxkcd.com/wiki/images/e/e4/1663_garden_Color_04_2_5d.png fish and columns] start to appear.
**[http://www.explainxkcd.com/wiki/images/d/d1/1663_garden_One_color_White_Blue_12h.png Blue white light] grow a sort of office theme, with desks, balloons and Cueballs. Moving towards white light [http://www.explainxkcd.com/wiki/images/d/d0/1663_garden_One_color_Between_Blue_White_and_White_5d.png Ponytail appears] with less office items together with cats (and now no Beret Guys in the pond but [http://www.explainxkcd.com/wiki/images/d/df/1663_garden_One_color_Between_Blue_White_and_White_8d.png lots of animals]).
**[http://www.explainxkcd.com/wiki/images/f/f7/1663_garden_One_color_White_9d.png White light] gives a forest of balloons with Megan holding her hands up.
**[http://www.explainxkcd.com/wiki/images/3/3e/1663_garden_One_color_Yellow_2d.png Yellow light] (somewhat right of the starting color) produce sale signs and snakes.
**[http://www.explainxkcd.com/wiki/images/4/4f/1663_garden_One_color_Between_orange_and_orange_red_8d.png Orange light] produce flying bird and flying Megans and on the ground snakes, turtles, linsangs and armadillos, plus tulips and wavy plants.
**[http://www.explainxkcd.com/wiki/images/0/02/1663_garden_One_color_Between_orange_red_and_red_8d.png Orange red light] (just left of red) produce lamp posts (without the top), in addition to the same desert theme as red with cactus and turtles. If it is very close to red the Mars rover appears (as in the example above). If it is a little longer from red, the platforms can form, which can then act as a catalyst for growth and create [http://www.explainxkcd.com/wiki/images/5/58/1663_garden_One_color_Orange_red_9d.png large towers] on top of cactus's.
*Nothing seems to be able to grow under several conditions:
**If no lamps are pointing towards the ground for instance because:
***All [http://xkcd.com/1663/#21374f9e-fbbd-11e5-8001-42010a8e0015 lamps are deleted].
***The [http://xkcd.com/1663/#4896b678-fbbe-11e5-8001-42010a8e0011 beam is laser thin.]
***The lamps points towards the sky without [http://www.xkcd.com/1663/#6a6a7be0-fbbe-11e5-800d-42010a8e0008 touching the ground.]
***The lamps are [http://xkcd.com/1663/#c75991f6-fbbe-11e5-8001-42010a8e0011 below the ground pointing down]. (In this case the one over the pond was not far enough down and a single water plant has formed anyway.)
****On the other hand if the lamps are below the ground but pointing up it can result in growth well enough as shown in this [http://www.explainxkcd.com/wiki/images/7/7c/1663_garden_Different_light_from_below_the_ground.png example] and this [http://www.explainxkcd.com/wiki/images/3/3a/1663_garden_Yellow_light_from_below_the_ground.png example].
**It was believed that if the lamps where very close to the ground pointing straight down there would be no growth.
***However this can be because only a very small area is illuminated
****In this [http://www.xkcd.com/#9733dff4-fbbe-11e5-8001-42010a8e0012 example] there are turtles under the red light in the pond, plants under the yellow and octopus, column and Cueball under the blue (from the time that columns could appear under pure blue light).
****Similar in this [http://xkcd.com/1663/#357a48d8-fbbf-11e5-8019-42010a8e0006 example] there are octopus (in the pond), deer/plants and a cactus from even lower lamps.
****Of course the lamp has to be so high as not to be underground as mentioned above.
**Also if lamps point towards the ground there can still only grow something from the ground [http://www.explainxkcd.com/wiki/images/3/3e/1663_garden_Two_light_on_small_area_nothing_outside_the_light.png where the light touches]. The growth can move outside the light cones up in the air, but the base has to be within an area with light.
**Similar with items that can grow new things on top of them like tree trunks or platforms, this will only happen if light shines on the relevant places.
***For instance the tall tree trunks can easily grow outside a light cone. Then leaves and branches will [http://www.explainxkcd.com/wiki/images/e/e9/1663_garden_One_color_Between_Light_yellow_and_yellow_3d.png only grow below] the point where the light hits
****Similar with platform, that [http://www.explainxkcd.com/wiki/images/3/3e/1663_garden_One_color_Yellow_2d.png grows partially outside] the light cone. More items will only appear where this lamp still hits the platform.
***One exemption to the rule mentioned here seems to be the bird raisers. The bird raisers are used to hold anything that flies up in the air. And the bird raiser it self needs to grow from either another bird riser or from a bird riser root (which in the end holds all bird raisers). This root has to have light on the ground to grow and thus have light on it self. But from the top of the bird raisers growing from such a root, items are able to grow even if the tip pf the bird raiser is not in the light.
****Thus flying items can appear to grow where there has [http://www.explainxkcd.com/wiki/images/4/4f/1663_garden_One_color_Between_orange_and_orange_red_8d.png never been light]!
****See much more about this under the description of bird raisers in the [[#Helper_structures|table below]].
**Of course lights can be moved and changed without destroying what has already grown there (or so it seems). So a tended garden cannot be used to determine this.
***This is why some [[1663:_Garden/Users_gardens#Locked_gardens_only_for_explanation_use|locked gardens]] have been set up where there will be no changes ever.
***Examples from above has mainly been taken from screen shots of these locked gardens.

===Grown items===
*Grown items may be highlighted by clicking on them. Selected grown items will be highlighted with a red circle, and appear slightly lighter then other items.
*Grown items may be "pruned" by the red X icon along the right of the window, or pressing the Delete key on the keyboard.
*Some items (such as the large tree) can be deleted in minor parts by selecting a branch or smaller set of leaves without deleting the entire tree.
*See the images (with links to xkcd) of all 250 items that can appear, here below in the [[#Items_in_the_garden|tables]].

===Growth development===
*There continued to appear new items that was not available on the release day.
**This lasted about a week (maybe 8 days).
**For instance many new items and animals like the columns and the owls started to appear after a few days.
**Also tulips and lightning poles did not appear at first.
***A last burst of new animals occurred about a week after release (either 11th or 12th of April). This burst included the following animals:
***Herons, Wadding birds, Sharks fins, jumping fish and flying fish plus actual flying fish (flying without water), armadillos and no less than 12 different linsangs (see [[1663:_Garden#Linsang_-_cat_like_animal|Linsang - cat like animal]]).
*But it also seems to change what might appear, so that the result of a particular color will change dramatically, not only by adding new, but also by not growing what used to be.
**A clear example of this is that for the first half week pure blue light resulted in lots of octopuses all along the ground and also Cueballs cheeking for rain.
**Later also columns appeared.
***But after a week the growth rate under blue light almost stopped, and it seems that octopuses now only grow over the pond to the left, and much less Cueball and no columns under that color.
**See details here: [[1663:_Garden/Screen-shots#Growth_speed_vs_blue_light|Growth speed vs blue light]].

===Debug mode===
{{notice|Anyone who can explain what the debug mode is, how it works, why it is there and why there is difference between the linden and the normal xkcd?}}
*By changing the url address it is possible to get into a debug mode.
**This may not work from for instance explorer, but seems to work from Firefox and chrome.
*Normal mode: http://xkcd.com/1663/#ID
**[http://xkcd.com/1663/#98dc3452-fcf2-11e5-8010-42010a8e0008 Normal mode example].
*At one point the Debug mode worked from this address http://xkcd.com/1663/?debug#ID
**But as can bee seen from this [http://xkcd.com/1663/?debug#98dc3452-fcf2-11e5-8010-42010a8e0008 example] it does not work any more but just goes back to normal mode.
*But there is still another version of the link which gives access to the debug mode: http://linden.xkcd.com/?debug#ID
**[http://linden.xkcd.com/?debug#98dc3452-fcf2-11e5-8010-42010a8e0008 Linden debug mode].
**In this mode each item can clearly be seen as the image is framed, and thus invisible lifter images for flying things can be seen.
***See this [http://linden.xkcd.com/?debug#d12a0932-faaa-11e5-8012-42010a8e0006 example].
**This last mode can be used to find the names of the [[1663:_Garden/Images#Images|images of each item]] in a garden.
***See this section on [[1663:_Garden/Images#How_to_find_new_links|How to find new links]].
***By preventing the browser from loading specific images (''e.g.'' with an ad blocker), all instances can be pruned temporarily.
*On the forum, [http://forums.xkcd.com/viewtopic.php?f=7&t=114415&start=600#p3959056 yan provides some jQuery] which can be entered in the javascript console to add an interactive sidebar listing the objects in the garden.

===Limitations===
*The beam produced by each lamp is normally restricted to spread between 0° (which results in no growth) and 95°. The "create new light" button chooses a random angle between 45° and 90°.
*Attempting to view several gardens simultaneously may cause some to hang on the "loading" image, likely due to the server refusing additional connections. The maximum number which can load successfully is usually six, but may be as low as three.

===Bugs===
*There have been several bugs mentioned already after the first day. Please include any spotted here:
**Also some problems that may now be fixed.
*May not run on some tablets or smart phones (i.e. touch-screen only devices).
*There are some browser versions of Chrome and Firefox where it doesn't run.
*The lamps may be invisible for a few seconds after loading.
*The whole page used to refresh at random intervals and lose the whole progress.
**It still does on April 5th.
**Sometimes (in some browsers?) the garden is reloaded when refreshing.
***This may though be because of the url which is a [[#Saving garden with url|link to a given garden]].
***See examples of this [[1663: Garden/Users gardens|here]].
***Seems to be dependent on the browser type.
*Some lamps jumped back to their starting position after a few minutes, without the whole page reloading.
*For a few hours after its apparition, the loading didn't seem to stop for some people, making them think that the rotating tree was the whole joke, with people expected to "relax" while looking at it.
*Occasionally invisible objects are added. They can be deleted, and they have bounding boxes in the [[#Debug mode|debugger]]: [http://linden.xkcd.com/?debug#d12a0932-faaa-11e5-8012-42010a8e0006 Example].
*Doesn't work over https, you have to use http instead.
*It is possible to save the image in Chrome and in Firefox, but not in Explorer.
**It is possible to save the visible portion of the image (in any browser) by pressing the Print-Screen key to perform a screen capture.
**But in Chrome the image is black where there is no light.
**In Firefox everything is visible, wth the light cones (in color) shown.
*Appears to have a memory leak at least in some Windows/Firefox versions, as keeping the page open for a long time will cause Windows to kill Firefox for insufficient memory.
**On the forum, Weeks tries to summon davean! [http://forums.xkcd.com/viewtopic.php?f=7&t=114415&start=320#p3951923]
*Does not work in many Linux versions.
*Tree trunks will sometimes grow endlessly without leaves depending on the lights hitting them.
*If you are dragging a light, the arrow, or the color slider when a refresh happens, the refresh will enter an infinite loop.
**This seems to cause corruption of the garden because refreshing the whole page will result in a loop that never loads the page.
**Clearing your local data for xkcd.com solves the issue but also makes you unable to edit your garden.
*On April 6, gardens viewed from [http://xkcd.com/1663/#7877bdfc-fc03-11e5-8001-42010a8e000c http://xkcd.com/1663/] links began to include double-size objects, while they appeared <s>normally</s> with different objects enlarged when viewed from [http://linden.xkcd.com/#7877bdfc-fc03-11e5-8001-42010a8e000c http://linden.xkcd.com/].
**Apparently some of the server's art files were <s>misdirected to the larger versions</s> replaced with new large images. [https://web.archive.org/web/20160407054439/http://linden.xkcd.com/art/rover.png] [http://linden.xkcd.com/art/2x-rover.png]
**New giant objects are still placed according to their original sizes. [http://forums.xkcd.com/viewtopic.php?f=7&t=114415&start=320#p3951908]
**This was suddenly fixed on April 7, possibly inducing browser memory issues at that time. [http://forums.xkcd.com/viewtopic.php?f=7&t=114415&start=360#p3952207]
***However, some giant images remained cached (where?) for a long time. [http://forums.xkcd.com/viewtopic.php?f=7&t=114415&start=400#p3952527]
*Although there are six bee images, they have not been reported in any gardens[[File:Garden_Bee_1.png]]

==Items in the garden==
*Below in the section are several tables displaying all the known images of items that may grow (appear) in the garden.
**They have been sorted based on type like characters, animals (by type), plants (by type), platforms, others and helper structures.
**In time each item will have a link to a screen shot where they appear.
**Also explanations for each item can be written in these tables
*For colors reference refer (also) to the numbers in this image: 
*[[File:1663 garden Numbered color scale 1-17.png]]
**The color under which a given item may grow should be noted.
***Particularly if they can grow under just one color if light (maybe a range, but with only one lamp lit as one specific color).
***But almost more important if some items needs more than one color
****Especially if the items base, the base on which they have to grow, needs another color than they do, as seems to be the case with flower blooms and the lamp to go at the top of the lamp poles.
*All the images can be seen without the table here: [[1663: Garden/Images|Images of items]].

|
*Here are the images of the bird riser and it's root.
**They only seem to appear in the orange color range.
**The riser is invisible (white) and would have to have a background to be seen (both versions are shown to the left). This will never be the case in the garden as the raiser does not show up in front of other black items.
***However, the risers can be seen using the [[#Debug_mode|debug mode]], and this is used as the example to the right.
***Also using the debug mode on this [http://www.xkcd.com/1663/#1e853af8-055f-11e6-8001-42010a8e000f garden] the [http://www.explainxkcd.com/wiki/images/e/e0/1663_garden_Color_13_2_5d_debug_with_count.png number of items can be counted] as shown in the link.
****From this link it is clear that there are three bird risers attached to two of the seven bird riser roots.
****Here only single bird risers are displayed, but they can be connected see below.
**The root can often be seen on the ground, but it can be hidden behind other objects.
***Also the root has the first short part of a bird riser above the root, which is invisible (by any means). The bird riser takes hold at the top of this invisible part. That it is there can best be seen by putting a frame around the image of the root, to see that it is twice as high as the root itself. Such an image is also shown to the left. (But the end can also be seen in the debug mode images).
*The riser are used to make items fly in the air.
**I.e. the five types of flying birds, the saucer, flying Megan and the two "actual flying fish", can attach them selves to the end of a bird riser.
**Whereas the risers need to have a root to begin, then more risers can attach to the end already existing risers, thus getting much higher up in the air than one riser (all the way up!).
**Risers can have any angles to each others, even going further down, which can explain birds and other flying objects touching the ground (even making an object be situated partially beneath the ground, like [http://www.explainxkcd.com/wiki/images/c/cf/1663_garden_One_color_Orange_6d.png this flying Megan] from this [http://xkcd.com/1663/#0d6bca62-fcf3-11e5-8019-42010a8e0005 garden] or maybe even outside the frame, see last example below).
**As opposed to anything else the light that creates a bird (or other flying item) does not need to touch the actually bird, but rather the place from where the bird riser is rooted.
***This indicates that the birds etc. can grow from light touching the base of the risers rather than the tip.
****Since many bird risers can grow in layers above the first riser it is clear that the bird riser does not appear with a bird on them in one go!
***There are many examples with [http://www.explainxkcd.com/wiki/images/4/48/1663_garden_One_color_Orange_9d.png birds] or [http://www.explainxkcd.com/wiki/images/4/4f/1663_garden_One_color_Between_orange_and_orange_red_8d.png flying Megan] "growing" outside the light, where no light ever was, as seen from some of the [[1663:_Garden/Users_gardens#Locked_gardens_only_for_explanation_use|locked experimental gardens]].
*When selecting a bird riser root all bird risers and all flying things connected to these will also be selected (and deleted if the root is deleted).
**Here are two examples from the same [http://xkcd.com/1663/#578b80bc-fd96-11e5-8001-42010a8e000a garden] where two different roots have been selected:
***In this [http://www.explainxkcd.com/wiki/images/b/b9/1663_garden_14_Between_orange_and_orange_red_15d_selected_bird_riser_root.png example] the selected root is hidden by the tulip in the red circle. Seven birds are selected both right and left of this root. (Two of them on top of each other).
***In this [http://www.explainxkcd.com/wiki/images/2/27/1663_garden_14_Between_orange_and_orange_red_15d_selected_bird_riser_root_Megan.png example] the root in the red circle is completely hidden by turtles etc. It connects to three birds and one flying Megan, showing that it is the bird riser roots that also connect to her.
**In this next example [http://xkcd.com/1663/#59246c86-fcce-11e5-8001-42010a8e0010 garden] the links between a root and four birds are displayed in detail.
***The [http://www.explainxkcd.com/wiki/images/7/73/1663_garden_SF_final.png first image] is just the normal garden view screen-shot (lamps deleted). 10 birds can be seen; there are six birds over the lamp post; two near the ground under the high platform; one near the right crown of the tree; and one to the left that looks like it is a part of the linsang. Several bird riser roots (at least five) can be seen on the ground from the middle of the platform and right past the cat (two under it) and then at the sign.
***In the [http://www.explainxkcd.com/wiki/images/8/8d/1663_garden_SF_final_selected.png second image] the root at the foot of the Sale sign has been selected. Four birds have been selected, spread out over the entire section with birds, including the lowest, the highest, the left most and one over the lamp post.
***In the [http://www.explainxkcd.com/wiki/images/7/73/1663_garden_SF_final_debug.png third image] debug mode has been used. All the long purple lines (of equal length) indicate bird risers.
***In the last [http://www.explainxkcd.com/wiki/images/3/35/1663_garden_SF_final_debug_drawing.png fourth image] the links between the root and the four birds have been indicated. A zero (0) has been written under the root. Then 1 indicates the single bird riser that goes to the right bird over the lamp post. Bird riser 2, 3 and 4 connect to each other from the root up to the highest bird right of the crown. Then bird riser 5 goes from that to the bird near the linsang left of the tree, and finally bird riser 6 and 7 goes straight back and down to the lowest bird near the ground.
****Several bird risers seems to go beneath the ground!
**That bird risers can go beneath the ground has already been show with flying Megan partly under ground.
***In this last example it is made clear that birds can then appear either under ground (or under the top of other structures blocking their view) or even totally outside the frame (as indicated above the bird risers seem to be able to sprout items outside the cones of light, as long as they grow in the light them selves).
***The proof for this comes in this [http://www.explainxkcd.com/wiki/images/1/16/1663_garden_Color_13_5d_debug_with_count.png example] with the debug version of this [http://www.xkcd.com/1663/#fa1b5c92-055e-11e6-8001-42010a8e000f garden] showing the count:
****At the time of [http://www.explainxkcd.com/wiki/images/7/73/1663_garden_Color_13_5d.png these images] there where only 8 visible birds
****But the count lists 20 birds, indicating that no less than 12 birds are hidden from view!

==Trivia==
*There are three different title text in this comic, as there are also one over each of the two icons.
**This is special as with some of the newest "game like comics" there are [[:Category:No title text|no title text]]!
**The normal one "Relax" is mentioned above in the main explanation.
**The other two are explanations for what the two icons in the top right corner does and appear when the cursor hovers over them.
***They are ''Create new light'' explaining that this icon introduces new lamps and
***''Remove selected (delete key)'', which explain that this icon can be used to remove (delete) selected items like lamps, plants or items. It also explains that the delete key can be used instead of the icon.

===Linsang - cat like animal===
*In the second week of release no less than 12 [http://www.explainxkcd.com/wiki/images/3/38/Garden_Linsang_1.png images] of the animal called {{w|linsang}} appeared [http://www.explainxkcd.com/wiki/images/1/1d/1663_garden_My_first_linsang_cat_like_creature_in_SC.png in the garden].
**See all of them [[1663:_Garden/Images#Images|here]].
*This animal was referenced in ''[[Thing Explainer]]'' in ''Tree of life'' where the animal is drawn in the ''cat-shaped'' section with the following caption:
::'''Almost cat'''
::This animal looks like a cat with a long neck. It's the closest thing to a cat that's not actually in the cat family.
::*Next to the section another one is drawn in front of Cueball (obvsiously it's Randall).
::*The linsang says "Mrowl?" and Cueball says "I wan't one!"
*Randall has in an interview discussed these [http://www.wsj.com/articles/randall-munroe-creator-of-xkcd-on-google-search-tricks-and-cat-like-creature-videos-1447945313 Cat-Like-Creatures] and in is quoted for saying
::Q: '''An animal I’m obsessed with is:'''
::A: The linsang, which looks almost like a cat but has this weird long neck. I find them both unnerving and adorable. I found some footage of one running; it’s like watching a cat video from a parallel universe.
::*The linsang is related to the animal {{w|Genet (animal)|genet}}, and here are two videos/photos of a genet running:

===Monday 4th of April release===
*Due to technical problems (or to make [[#April Fool's header text|fools of his fans?]]) the comic did not go live until Sunday evening (after midnight, so technically first on '''Monday April 4th''').
**There was thus no Friday release in the week before
**So the Wednesday comic [[1662: Jack and Jill]] got a lot more attention than it would usually have had.
*This comic thus turned in to the Monday release instead, as no other comic was released later that Monday, as this would have taken attention away from this very special comic.
**But it was called the ''April 1st comic'' and later the ''Friday comic'' in the [[#April Fool's header text|header text]] displayed at the top of xkcd to explain why there was no Friday comic.
***A header text continued to stay a the top but changed two more times until the release past midnight Sunday in the US. It was even past midnight {{w|Pacific Time}}, but not yet on Hawaii.
**There were thus only two comics released in the week before this Monday, which may be the first time since xkcd went live on {{xkcd||xkcd.com}} in 2006.

===April Fool's header text===
*There is some debate as to whether this comic is an April Fool's comic or not.
**Was instead the April fool's joke the text written above the comic in the header of xkcd?
**There is reason to believe this was [[#April Fool's comic|not the case]] based on among other thing these header text.
*Below it a list of the different header text displayed from Friday until the comic was just released.

===April Fool's comic===
*This comic '''was indeed supposed to be''' the Friday 1st of April, April Fool's comic!
**This statement is based on several things, which can can be deduced from the above header text and the subsequent issues with the many [[#Bugs|bugs in this comic]].
*It is clear that this comic did actually come out as promised, at least as promised in the third message about release on Sunday night.
**It is also clear that it is regarded as the Friday comic, even in the last update before the release, which was two days after April 1st.
*It is also clear that this was a very complex comic, and it is realistic that Randall did have problems with making it work.
**On day two there still seemed to be several minor bugs, which seemed to improve over time so Randall was still working on it after release.
***But then new bugs appeared when the next comic was released.
*Both of the last two April Fool's comics, [[1350: Lorenz]] and [[1506: xkcloud]], have had no real meaning or joke in the comic. The jokes appeared from user input, and here it comes from waiting.
**This makes people who spend too much time on these comics ''April Fool's'' (or if they rather wish to be called a ''nerds'' than fools, then they can claim to have been a victim of [[356: Nerd Sniping|nerd sniping]]).
**So, even if Randall ''did'' play a joke on people who [[Talk:1662: Jack and Jill#What happened to Friday's comic|eagerly awaited the comic]], then he did deliver as promised a spectacular comic Sunday night.
*There are several reasons to believe that Randall would have preferred the comic to get out on Friday April 1st.
**Apart from it being a time consuming comic that in it self is April Fool's comic material, then by getting it out Friday this special comic, which he obviously have used a lot of time to prepare, would have had one more day as the first comic.
**Getting it out before a weekend would have let many more users spend time looking at their garden. Now many would not spend enough time to appreciate the comic, as it came out right when the new work week began.
***And it is a very complicated comic that just to get to understand how to really use it could take a days time even for someone with time.
***And this is not talking about how the comic works, but just how to use the program, i.e. the whole [[#Functionality|functionality]] of the comic is way more complex than even a game like [[1608: Hoverboard]].
**And before next weekend two more comics were released taking some of the focus away from this one too soon, and also before the next weekend.
***Of course die hard fans will not forget this one, but many xkcd fans may only come by in the weekend etc. and such a hard to come by comic like this, that demands patience and that you return does not profit from being bumped down to number three as it would be next Friday.
*Randall lives of his fans goodwill and to deliberately make a pun on them like this would probably not seem like a good business proposal, apart from the fact that the comic now gets less attention than by coming out before the weekend.

251: CD Tray Fight

2013-12-20T13:30:52Z

108.162.250.114: /* Explanation */

{{comic
| number = 251
| date = April 20, 2007
| title = CD Tray Fight
| image = cd_tray_fight.png
| titletext = This is silly, of course. The enemy will be born in the network.
}}

==Explanation==
This comic refers to the behavior of a {{w|Optical_disc_drive#Loading_mechanisms|tray loading optical disc drive}} of a desktop computer. When the tray is opened and the user is reaching for the disc, a process or task on the computer can, at that exact inopportune time, request that the disc drive close its tray. Alternatively, accidentally bumping the open tray may engage the auto-close feature, resulting in the same scenario.

This results in a sort of "tug of war" between the user who is trying to remove the disc and the CD drive trying to retract.

With a reasonable amount of force by the user, most drives will detect the resistance and give up trying to close as a safety feature, ejecting the disc again.

A "Robot war" is a recurring theme in science fiction where humans develop robots that become self aware and start a war against humanity.
A well known example of this theme is found in the {{w|Terminator franchise}} where, as the title text suggests, a military computer network ({{w|Skynet (Terminator)|Skynet}}) becomes self aware and starts a world war to kill all humans.

==Transcript==
:[Cueball is standing, holding a CD tray which is half-in his computer. There are other CDs on the floor.]
:Cueball: Hey. Hey! Stop retracting my CD!
:I feel uncomfortable when my computer physically struggles with me. Sure, I can overpower it now, but it feels like a few short steps from here to the robot war.

1306: Sigil Cycle

2013-12-20T13:29:03Z

108.162.250.114: /* Explanation */

{{comic
| number = 1306
| date = December 20, 2013
| title = Sigil Cycle
| image = sigil_cycle.png
| titletext = The cycle seems to be 'we need these symbols to clarify what types of things we're referring to!' followed by 'wait, it turns out words already do that.'
}}

==Explanation==
{{incomplete|This is just a skeleton, every detail is missing and probably some parts are inaccurate or plain wrong}}

"In computer programming, a sigil (/ˈsɪdʒəl/ or /ˈsɪɡəl/; plural sigilia or sigils) is a symbol attached to a variable name, showing the variable's datatype or scope, usually a prefix, as in $foo, where $ is the sigil."[https://en.wikipedia.org/wiki/Sigil_%28computer_programming%29]

Usually, the link [http://www.xkcd.com/ http://www.xkcd.com/] goes directly to the latest comic, however in this case the homepage redirect seems to have not been updated, so [http://www.xkcd.com/ http://www.xkcd.com/] goes to comic 1305, while the most recent is 1306 and it can only be accessed through the link [http://www.xkcd.com/1306/ http://www.xkcd.com/1306/].
The link to the "next" comic in 1035 should move forward to comic 1306, however this only works if comic 1305 is accessed through [http://www.xkcd.com/1305/ http://www.xkcd.com/1305/] and not if it is accessed through [http://www.xkcd.com/ http://www.xkcd.com/].

*** fixed ***

;{{w|QBASIC}}
: Variables of type string end with the $ symbol. Other symbols are used (% for integers, ! for single-precision, # for double-precision and, in some versions of BASIC, & for long integers), however the usual QBASIC program will use only the $ symbol and not any of the others, as the default type if no symbol is used is double-precision and that's OK for most numeric uses.

; {{w|C++}}
: Variables have no strange symbol. They are just words with regular letters.

; {{w|bash (Unix shell)|bash}}
: This is not strictly a programming language, but a Unix shell. However, the shell command syntax is rich enough to be able to write simple (and sometimes really complex) programs, usually called shell-scripts. In this language, all variables start with the symbol $.

; {{w|Perl}}
: Variables of simple types in Perl start with $, and arrays start with @.

; {{w|Python (programming language)|Python}}
: Variables have no marker symbol.

; {{w|Google}}
: In the beginning of Google, it was a search engine. However, it now includes many things, in particular a social network called Google+.

; {{w|Twitter}}
: Twitter channels are identified by the symbol @.

; {{w|Hashtag}}s
: In some microblogging messages, a # sign can be prepended to important words to mark them as "keywords", so the message can be searched for those words.

==Transcript==
{{incomplete transcript}}
*Y axis: Odds that the words I type will start with some weird symbol
*X axis: Time
*Data labels: $QBASIC, C++, $BASH, @$PERL, PYTHON, +GOOGLE, @TWITTER, #HASHTAGS

1305: Undocumented Feature

2013-12-18T12:10:29Z

108.162.250.114:

{{comic
| number = 1305
| date = December 18, 2013
| title = Undocumented Feature
| image = undocumented_feature.png
| titletext = And it doesn't pop up a box every time asking you to use your real name. In fact, there's no way to set your name at all. You just have to keep reminding people who you are.
}}

==Explanation==
{{incomplete|Incredibly short}}
Cueball (presumably) has found a secret support chatroom. Eventually, the comic comments on how nothing is forever, but eventually subverts this by attacking Facebook's video ads that had been announced the day just before the release of the comic.
Over years he and the other members of the chatroom become friends in their secret hideaway. The chatroom seems to serve no purpose other than perhaps being some sysadmin's source of entertainment.
Cueball/the narrator then develops an existential outlook, contemplating the relatively short life of the chatroom server and also the lives of its small group of users.

The fact that it has no video ads or even names for its users is a feature of the simpler times of the internet.

The title text expands on this by mentioning the pop-ups on Youtube asking for your channel/user name. Youtube would like to make you use your real name. On Facebook you're supposed to use your real name anyway.

==Transcript==
:[A support window is shown.]
:An old Windows utility has an undocumented feature. If you open "help" and click on the background, you get dropped into a "support" chat room.
:Support Window: Launching support forum...

:[An active conversation between two people is shown.]
:Only a few of us ever found it. But we became friends.

:[Cueball and Ponytail are at computers.]
:We kept launching the program to check in. Eventually some of us were running VMs just to keep accessing it.

:[Another conversation.]
:As the Internet aged, so did we.

:[Three question marks.]
:We don't know who runs the server. We don't know why it's still working so many years later. Maybe we're some sysadmin's soap opera.

:[A group of people are shown in a bubble.]
:It will probably vanish someday, but for now it's our meeting place. Our hideaway.

:[The bubble is now smaller, and some parts of a web are shown.]
:A life's worth of chat,

:[More of the web is shown.]
:Buried in the deep web.

:[A flat landscape is shown with the sun at the horizon.]
:But even if it lasts forever, we won't. When we're gone, who will remember us?

:[Cueball and Hairy are shown standing together in a bubble.]
:Who will remember this strange little world and the friendships we built here?

:Nobody.

:[An empty bubble is shown.]
:This place is irrelevant. Ephemeral. One day it will be forgotten.

:[The bubble starts to fade away.]
:And so will we

:[The bubble has almost completely faded away.]

:[The bubble is now completely gone.]

:But at least it doesn't have fucking video ads.

1304: Glass Trolling

2013-12-17T04:15:52Z

108.162.250.114: Ohh -> Ooh

{{comic
| number = 1304
| date = December 16, 2013
| title = Glass Trolling
| image = glass_trolling.png
| titletext = Plus, when someone finally grabs your glasses and stomps on them, it costs way less than $1,500 to replace them.
}}

==Explanation==
{{incomplete|Is there really much to say?}}
{{w|Google Glass}} is a set of glasses frames worn like typical glasses that features an optical display and internet connectivity. It responds to voice commands starting with [https://support.google.com/glass/answer/3079305 "OK ''glass''"], for example to initiate video recording or to check tomorrow's weather. Strangers and other people surrounding the user would often find it annoying to hear someone talking to "himself", or to ''Glass''.

[[Cueball]] is checking tomorrow's weather and says "OK, ''glass''" while he is only wearing regular glasses. Apparently this is even more annoying to the bystander than if Cueball actually would wear a ''Glass''.

In the title text, a bystander is eventually fed up with the annoyance and smashes the glasses to the ground. If they were an actual ''Google Glass'', they would have cost a fortune to replace, regular glasses are much less costly.

The "OK, ''Glass''" keyword is not useless outside of ''Glass''; In the ''Android/iOS'' app ''Google Now'', "OK, ''Glass''" is also valid instead of "OK, ''Google''" to initiate a voice command. It's likely that Cueball uses this app because he holds a smartphone in his hand.

This is another strip in the [[My Hobby]] series.

==Transcript==
:My Hobby:
:Cueball: Ok, Glass, check tomorrow's weather.
:Cueball: Ooh, snow!
:Off-frame-bystander: Oh my god, it's somehow even ''more'' annoying than if you had it.
:Saying "Ok, Glass" before everything while wearing regular glasses.

::: The 'favourite' apostle was John the Evangelist though. http://en.wikipedia.org/wiki/Disciple_whom_Jesus_loved . The other biblical clue here is 'with your own hand you have done all this' - Judith 15:10. If that's Judith1510 then the 'name and shirt number' is 'Judith15'. The TOS/earlobes clue seems to be "Spock's brain" and "Spock's (ears?)". And the Michael Jackson one is (obviously) ABC123.

::: Given that name1 is two blocks long, I would guess that the apostle's name is going to be eight characters long, with the second hash block being 1+seven spaces (or nulls if Adobe pads it with nulls and not spaces). But then again, as the only disciple with a name eight letters long is Thaddeus maybe not {{unsigned ip|141.101.99.214}}

:::: "St.Peter" is 8 characters, and having a "special" character (the period) makes it a good choice for passwords that might require 1 non-alphanumeric character (and ban spaces). [[Special:Contributions/141.101.99.223|141.101.99.223]] 11:47, 4 November 2013 (UTC)

"Sexy earlobes" makes me think of [http://misswiu.livejournal.com/5385.html "The ABC of Aerobics"], but that would make that Shirley Clarke, and nothing in Star Trek has anything to do with Shirley that I am aware of, except possible [http://en.memory-alpha.org/wiki/Ruth Shirley Bonne as Ruth]. I skimmed a list of episode titles, but nothing jumps out at me as particularly earlobish. [[Special:Contributions/108.162.219.187|108.162.219.187]] 11:20, 4 November 2013 (UTC)

:Sexy earlobes might have something to do with Ferengi, but they didn't appeared in TOS. 141.101.99.214's idea is better. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 11:42, 4 November 2013 (UTC)

Note that you should not ever use cipher in {{w|Block_cipher_mode_of_operation#Electronic_codebook_.28ECB.29|ECB (electronic codebook)}} mode, i.e. encrypt each block separately and independently, but use chaining. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 12:15, 4 November 2013 (UTC)
