Magician lays out a grid of nine cards and has a prediction. Corner cards are face up. The rows and columns are folded together until you have one stack of cards. The only face up card is the prediction. I figure this is an old self-worker in print somewhere. Anyone have a name or a source?

I asked for sources on the Genii Forum for a similar effect. No doubt they apply towards your effect as well.
