In the new October 2005 issue of Genii, Karl Fulves (about whom I've written here before) writes up a great variation of the classic "Moe's Move-A-Card" routine, called "Moe's Memory". In the new Fulves version, you actually have two people switch cards in a shuffled deck, and you are able to determine them.

Despite the effect, there's no memory work involved. I don't want to give too much away, but those who favor the use of the Epitome Location should check this out.

Also during this month, you can check out Doug MacGeorge's variation of "Moe's Memory", which he calls the "30 second Memorized Deck", for free, courtesy of Greg Webb Magic e-Books. It's only free during October 2005, so get over there and download the PDF file as soon as you can!
