    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 repair their larger-scale morphology: https://www.youtube.com/watch?v=XheAMrS8Q1c

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

    This is the future of scientific publishing, pdf is so boring.

    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?

    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 between the particles to exploit low contrast areas in the data

    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?

      If you look at the texture demo with the zeros, it looks a bit like lipid membranes merging/splitting as they stabilize more or less around a particular size.

      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.
