LIFE is a cellular automaton devised by British mathematician John Horton Conway in 1970.
(It plays itself on an infinite two-dimensional grid of square cells, each of which either live or dead. At each move:
1. Any live cell with fewer than two live neighbours dies "of loneliness".
2. Any live cell with more than three live neighbours dies "of overcrowding".
3. Any live cell with two or three live neighbours lives on to the next generation.
4. Any dead cell with exactly three live neighbours comes to life.
All births and deaths happen simultaneously in each generation.)
We show one state of a GLIDER, a pattern that moves off in a straight line.
This has been adopted as an emblem for computer hackers (the good guys, not crackers - criminal hackers).
Wear or display one of these and make contact!
Patterns generated by a Life-like program are also available.
