Conway's Game of Life.   J.H. Conway came up with this thing in the late 1960s, and that's about all I know about the subject.  The population of let's call 'em critters grows in an array.  Picture one little critter with a neighborhood of 8 neighbors, those other critters that may possibly be surrounding him.   If a critter has 2 or 3 neighbors, he's fine and dandy and stays that way. If a critter has anything other than that, he dies, either from overcrowding or loneliness or what not.  If there is an empty space with 3 neighbors, then a new critter will move in there.  And that's it, that's all it does.

Yes!  It runs under its own power, finally.  Blessed be to the gods of swings.

New simulation : starts a new simulation with a new initial population.

Pause : pauses.
