Regeneration after damage is impressive; users enjoy cutting the lizard demo

Found it much interesting that i could mess up a pattern enough that it couldn't re-form. Would be fun if selecting a new pattern didn't refresh the image as it is. Although…

Connects to Michael Levin's work on morphogenesis
From 2 comments
On the outside it looks very similar to what Michael Levin found on electrical communication between living cells. There too, the organism's cells were able to structure and…

Regeneration only works from the egg-like initial condition; switching rules mid-rollout breaks morphology
From 1 comment
Indeed! The system has good regeneration capabilities but it certainly has limits. The particles can only grow reliably if they start from the egg-like initial condition. If we…

Super cool work!!! Do you think it would be possible to do something like cell division here?

Could it be used for texture synthesis?
From 1 comment
could something similar be used for texture synthesis ? of course the particles will need to be arranged in a grid and everything, or maybe recreate the texture by interpolating…

Why are cellular automata suddenly everywhere?
From 1 comment
Can someone tell me why cellular automata are suddenly everywhere? I've seen ~10 articles regarding them in the last month.
