These are cool
Because anything to do with Cellular Automata is cool.
These are one-off light sensitive lights… the change according to their environment… and if you put them together, they change according to each other.
And that is the thing with little automous feedback systems when they get together… the inevitably talk to each other, and inevitably create higher-levels of complexity – and that is why fractals look the way they do, and why you get those repeating triangular patterns on textile cones
