"Star Wars" is a cellular automation, quite akin to, but with the rules a little different: a cell survives if it has 3, 4 or 5 alive neighbours (this would have been indicated by "345" in the rule code, which SJ has written as "352" for some reason), a cell is born if it has 2 alive neighbours (indicated by the 2) and also, if a cell doesn't survive, it doesn't die instantly - it fades out gradually, scrolling through 4 stages, the first being fully alive, the last being dead.

You can explore such automata using Golly.
