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?

I think I've seen it before that too, from HN.

Very cool, thanks for the links! Are you affiliated with the project?

There's a deep motivation behind all this, which is to try to understand the pattern formation mechanisms that appear in nature and get harnessed by organisms.

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.

If you could, I imagine that the hard part would be proving it correct.
All you'd really need to do is to find a way to simulate 'regular' (discrete) life. Setting it up would be a major pain.

That's the case for our universe as well, for example d^2x/dt^2 due to gravity for a piece of material is dependent on all other material in the universe.

Thank you, mind blown! Downloaded "Golly" ( http://golly.sourceforge.net/ ) and ran HashLife/metapixel. Life simulating life, and it runs in real time.
Mind blown pretty much describes what I felt like when I first came upon it. After spending a good bit of time optimizing 'life' having your ass handed to you by a large number of orders of magnitude courtesy of mr. Norvig is a good lesson in humility.

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.
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.)
