    Other sized w must be a power of 2 and i must be at least w**2+r+1 (r=neighbourhood radius) to allow the sliding window to correctly initialise, otherwise a bad sum will propagate throughout the grid usually causing everything to die.

    👍 Thanks for the explanation!
  • u/tomxor
    hmm the larger than necessary i seems to be introducing artifacts... change to i=w*w+6 if you want to see the pure rule.

    Woow! I remember it from the The Powder Toy game
