Page 1988 et seq.

Personal Comment: He, how can you not like that. This is super fun. And the message on the back could nearly say anything. It could say "The card is on top", or "The card is the Six of Diamonds"... whatever. This is one of those ideas that can applied to a whole number of effects. All you need is the right surface. I even know of one magician who actually uses this so often that he has the worm printed on his business card. So his business card goes for a ride. Think of the possibilities.
