Conway's Game of Life
The Game of Life, also known simply as Life, is a cellular automaton
devised by the British mathematician John Horton Conway in 1970.It
is a zero-player game, meaning that its evolution is determined by
its initial state, requiring no further input. One interacts with
the Game of Life by creating an initial configuration and observing
how it evolves. It is Turing complete and can simulate a universal
constructor or any other Turing machine.
