Cool. They do sound like great mentalism effects.
btw, I've been working on a version of a three person card reveal. Deck borrowed, shuffled, examined. Spectator 1 shown a card, card placed on table. Spectator 2 shown a card, placed next to first. Third spectator also shown a card and placed with other selections. The three cards are squared up into a pile on the table. The cards are named by the spectators at the same time. Card the specs. name is the same. Saying that they couldn't have possibly seen multiple cards, the performer asks a spec. to turn over the selections on the table. The cards have transformed into the one single card that was named.
Inspired by this thread.
I'm just working on getting a streamlined handling now.
