This rule sets the new state of each cell to the modulus sum, base 9 of its immediate 8 neighbors plus itself. A rule by Alastair Couper. ModulusN2 Exploding Add up the von Neumann 5 neighbors and return the sum mod 2. A rule by Dave Hiebeler. RandomWalk Chaotic RandomWalk Cellular Automaton in Margolus neighborhood.
All cells move randomly on the grid.
A rule by Brian Behlendorf, November 1999. Rug Exploding Rug rules are averaging rules using the full range of 256 possible states. To update itself in a Rug rule, every cell takes four steps. Every cell calculates the sum of its eight nearest neighbours' states. Every cell calculates the average neighbour state by dividing the sum by eight and throwing out any remainder.
