Day & Night is a Life-like cellular automaton in which cells survive from one generation to the next if they have 3, 6, 7, or 8 neighbours, and are born if they have 3, 4, 6, 7, or 8 neighbours. Day & Night is the most well-known self-complementary rule. That is, if all grid cells have their on/off state exchanged, the history of the pattern is the inverse of the history of the original. Nathan Thompson explored the rule starting in April, 1997, and David Bell discussed the rule in detail the following November.
