This general subject was covered in an earlier Genii forum thread at: http://geniimagazine.com/forum/cgi-bin/ ... 528#000003
I believe Joe is right that the effect is Alain's Romeo & Juliet but I have seen the lecture notes referenced as "Mind over Matter.
Also I believe that it is closer to Barrie's ungaffed effect called "Any Card at any Number" on page 257 of Barrie's first book on Theater of the Mind. (I haven't seen Theater of the Mind Part 2 yet.) The sleight at the end of both effects seems to be different.
You may have a difficult time getting Alain's lecture notes however there is a reference in the thread listed above that you can try.
