Fredkin’s Self-Replicating Cellular Automata: Sum the neighbors, modulo 2, and assign to the cell on the next timestep. Astonishingly this allows patterns to replicate in multiple directions across the plane. https://cellpylib.org/fredkin.html https://cellpylib.org/fredkin.html Works with any kind of lattice. Even works in 3D.
