World's First Game-Playing DNA Computer

An anonymous reader writes "NewScientist.com posted an article today about the first game-playing 'computer' powered by DNA logic. An interesting read, although not at all a practical alternative for those looking to replace their PlayStation2 with the next great platform." The machine is "...an enzyme-powered tic-tac-toe machine that... uses a complex mixture of DNA enzymes to determine where it should place its nought or cross, and signals its move with a green glow."
