Loop for Mac

From Javelin Systems:

Chris Langton's cellular automata "loops" reproduce in the spirit of life. Beginning from a single organism, the loops from a colony. As the loops on the outer fringes reproduce, the inner loops -- blocked by their daughters -- can no longer produce offspring. These dead progenitors provide a base for future generations' expansion, much like the formation of a coral reef. This self-organizing behavior emerges spontaneously, from the bottom up -- a key characteristic of artificial life.

Don't Panic -- When the artificial life tries to leave its petri dish (ie. the screen) it will (usually) die... The loops are short of "real" life because a general purpose Turing machine is not contained in the loop. This is a simplification of von Neumann and Codd's self-producing Turing machine. The data spinning around could be viewed as both its DNA and its internal clock.
