Multi-state cellular automata can be used to create intriguing visual effects. Today and the next few days I will give examples of such visuals. I start with an automaton I discovered yesterday, defined by the following rule: if the top-left neighbour has a value greater than the bottom-right neighbour, decrease the value of the cell (mod N); otherwise, set the cell’s value to the successor (mod N) of the average of the values of the von Neumann neighbours. This produces the following result (with N = 24):

I call it “Fuzz with dust”.
