I could see Game of Life as part of a DIY steganography scheme. E.g. I tweet a picture and have some numerals in my tweet called N. You download the picture and convert it via an agreed on protocol to a game of life board, then advance the board by N times. Then you convert the board back to bits and then to text, and find somewhere in the text a "Message begins: XXX. Message ends." Sequence. I wonder if you would be able to hide messages in superficially normal pictures like that.
