This is really very impressive. The design of the stick figure to allow it to release a glider that ascends upwards (the "soul" rising to "heaven" or whatever) with the body decaying - that's a hard thing to get right using just the Game of Life rules.

:::::The Game of Life has been researched a lot. One sub-problem is finding an arrangement of cells that cannot be produced by a prior arrangement of cells. They are called Garden of Eden patterns, and the known ones are not small. Glider generators are rather common, so it is most likely that the initial pattern was created by working backward from an existing glider generator.[[Special:Contributions/173.245.54.125|173.245.54.125]] 17:33, 14 April 2020 (UTC) | :::::The Game of Life has been researched a lot.

:Golly uses a grid of arbitrary size by default. It can very easily be verified to at least ±2<sup>10000</sup>. (Note that it also includes finite rectangular and toroidal grids.)

No computer [Citation Needed] can run an ''actual'' infinite grid, but with some intelligent bounding you can mitigate early signs of problems by maintaining "bubbles" of cells with offsets. You get into problems once you start machine-gunning out gliders (offsets will eventually overflow or awkwardly lose precision, depending on the var-types used; and maintaining a longer and longer bubble, or more and more bubbles just above glider-sized, is probably your other challenge) but it's probably good enough for most purposes. If you somehow have finite patterns that move out in huge (wasteless) cycles from the 'origin' and hold that path until enacting hugely-delayed doglegs (mathematically, it must be a point no further away than can be reasonably enumerated by the bits of information contained within each formation, and significantly less as it'd be a far less efficient count-down cycler than any folded LFSR, but it's ''imaginable'') to meet again at some arbitrary (though deterministic and replicable) distance out in the far far reaches of your abstracted bubble-land then it's possible you could ''pretend'' you have infinite space.

[[User:ProphetZarquon|ProphetZarquon]], do you have a source for your claim that the main point of Conway's creation of Life was to study the edge effects? [https://conwaylife.com/wiki/Conway%27s_Game_of_Life The page for Life on its own wiki] describes the Life grid as "infinite" and only mentions edge effects as inaccuracies to be avoided, and [https://www.youtube.com/watch?v=R9Plq-D1gEk this Conway interview about Life's creation] doesn't mention edges at all. | [[User:ProphetZarquon|ProphetZarquon]], do you have a source for your claim that the main point of Conway's creation of Life was to study the edge effects?

I really think this should not be regarded as a Covid-19 comic, since it's a memorial one and the cause of death is not important for this comic.

:Agree with the others, this is a memorial comic, NOT a COVID-19 comic. I feel like too many comics are being forced into the COVID-19 theme, when they have little to no relation.

It would seem remarkable if Randall was able to create this starting pattern at such short notice. If it's copied from somewhere, we should provide that detail.

:I do not know if it is taken from another place or a common/known pattern (the comments above seem to suggest otherwise), but it is not uncommon to have an obituary / memorial in stock for elderly persons of relevance. So it might be possible, that e.g. Randall played around with putting stick figures into a simulation, and accidently found this, deciding to keep it somewehere in his archive for this occasion. The seperation of the decaying body and the everlasting part going upward is actually obvious enough to connect with the idea to use it for this occasion. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 10:36, 15 April 2020 (UTC) | :I do not know if it is taken from another place or a common/known pattern (the comments above seem to suggest otherwise), but it is not uncommon to have an obituary / memorial in stock for elderly persons of relevance.
