It does seem more "organic", if you will.

It does. Still I think the point of game of life is not to look organic but to make complex thing from very simple rules. Like supposedly the universe we live in. Conway's game of life would look organic if you zoomed out enough, no computer can do that of course.

How far do you want to zoom out?

Aren't cellular automata in continuous space just PDE's? If so, what is the equation being integrated? EDIT: found the paper: http://arxiv.org/pdf/1111.1567v2.pdf

Not quite; the values at every point are boolean, not floats. (From the link) The algorithm is explained here: http://www.youtube.com/watch?v=iyTIXRhjXII

It's confusing because several algorithms are explained, but I believe they're actually floats in this version.

Also it's not a normal PDE because ∂f/∂t is permitted to be an arbitrary functional of f restricted to a fixed-diameter neighborhood of the point, not just an infinitesimal neighborhood.

Hey guys, check out the Conway's Game of Life Code Garage project on LearnStreet: http://www.learnstreet.com/cg/simple/project/conways

I'm not logging in with Facebook to see your site, about which I know nothing, when you haven't even sold me on its relevance to the topic under discussion.

no computer can do that of course. we are getting there - http://www.youtube.com/watch?v=xP5-iIeKXE8

Outstanding, thank you for this. Worth a post on its own don't you think?

All the way.

Pinchyfingers submitted this link:

(http://news.ycombinator.com/item?id=4642628) which goes to a Youtube video of a game of life in a single line of APL. It's a really nice description of the code too. (It's a sale pitch for dynalog - but the best kind where they're just using the tool to do something neat and not pushing their URLs at you.)
