Neat. I thought it was a peculiar visualization of Conway's Life at first, but it's got a more complex set of rules. The presentation and controls are pretty good. I'd like to be able to see which organism type is which, and especially be able to zoom in on any new ones.

It's been running for me for a few minutes at top speed and it hasn't gone over 8 celled organisms, but it had an explosion at some point where it went from just a few species to over 200. I wonder if the algorithm could be memoized like in hashlife.
