Show HN: Neural Particle Automata

[esychology]

Neural CAs model self-organizing pattern formation on grids. Now the grid is gone. Each cell is an agentic particle that can move freely in space and change its state.

While each particle follows a simple shared rule, many together can grow complex morphologies or form intricate patterns. The resulting particle system as a whole can regenerate from damage and exhibits surprising emergent behavior.

Try cutting the lizard and watch it heal itself!

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 maybe that's a requirement?

This is super cool, great work. Is there a video or demo of the 3D point cloud "gaussian splat" like experiments?

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

[esychology]

Thanks! Yeah I think it should be possible though it requires making the cell division/splitting a differentiable operation. But nontheless, this is indeed a very interesting and promising direction to pursue.
