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.

Well, generations don't have to be rendered in realtime, so you could just grab some high cpu instances on AWS and compute really large sizes. For example, this guy made a turing machine, and it's pretty huge: http://rendell-attic.org/gol/tm.htm

And that was in 2000. I'm sure we could do extremely large boards now.

> Conway's game of life would look organic if you zoomed out enough,

Are you sure? This isn't obvious to me.

check out hashlife and some of the larger landscapes.

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.

hashlife is a pretty brilliant algorithm. basically it sort of memoizes patterns at different scales. highly recommended to check out the details of how it works.

Just check the frontpage again in a few years.

How far do you want to zoom out?

All the way.

"Make complex things from simple rules" - that's pretty much defining organic in this sense.

no computer can do that of course.

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

That's the video in the same blog if you click "Previous": http://www.jwz.org/blog/2012/05/turtles-all-the-way-down-or-...

It had one, 4 months ago. No comments, only 4 points.

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

And you can run that in real time on a desktop. The secret is a hash life approach.

Em, it's called "Game of Life" because the whole point was for it to look and behave _organic (Wikipedia: "Conway was interested in a problem presented in the 1940s by mathematician John von Neumann, who attempted to find a hypothetical machine that could build copies of itself").
