This page demonstrates Conway's Game of Life in 24 bit RGB. There are actually 24 simultaneous "games of life" being played on the above board, one for each bit in a 24 bit RGB color value that is the background of the square. However, since we naturally think of white as the "dead" color and black as the "alive" color, the bits have been flipped in this demonstration so that 0 represents alive and 1 represents dead. Thus #fff, which is white, represents a cell that is completely dead, even though all of the bits are "on".
