A book that plays tic-tac-toe with you

Tic Tac Tome is a book that's smart enough to play tic-tac-toe with you – no batteries required. You start on the first page by deciding which of the 9 spots to place your X. Then turn to the indicated page number to see where the book places its O. And so on, until one of you wins (or you have a cat's game). To let the book start first, flip the book over and start from the back page. The photos above show a game started by the book and ending in a cat's game. I can't wait for the Chess version – it'll be a couple of hundred million pages long, so I've cleared a spot on my bookshelf for it. (via Wink)
