Most of the rules displayed here and in the Hexagonal Extension are taken directly from Collidoscope, where they were first introduced. Collidoscope runs its rules in much larger screen-sized universes at video refresh rates, making it easily an order of magnitude faster than Modern Cellular Automata!
To experiment further with a rule select, copy, and use its specification in either the Author tool or the AuthorXY cellular automata comparison tool. Pages: 1 7 8
