I wanted to simulate the growth of snow crystals using a modified cellular automaton. A well-known cellular automaton is Conway’s game of life. This should give me some fractal structures of hexagonal symmetry. However, due to false reasoning or programming mistakes I got something else, shown here. I will correct these problems. But I like the present results too. A welcome to the unexpected in computer graphics!
Note that the images suffer from inaccurate compression and decompression.
