I will re-read the section on the center tear and will let you know how it turns out.
I looked into Kolassal Killer, based on your suggestion. I find it to be a very interesting effect. The pumping of the audience fits in well with the character I portray (A mentalist developing his ability. Not perfect, proud, nor all-knowing, But, humbly, I always seem to get it right, and I am often surprised, myself.). I can see myself doing the pumping. However, the written note on the card that shows you knew it would be off by one is a turn-off.
Tell ya what: I'll pm you a way to get around that.
I am working on an effect where I cut to any card named by a spectator.
I'll PM you a way to do that.
The version that you do, Derren Brown has a routine like it. I'll pm you the details, let me know if I'm wrong.
Regarding Uri Geller effects - Excellent suggestion! I use spoon bending. Recently purchased Liquid Metal which has some very nice moves and is adding to my presentation. At a restaurant or banquet, this is a fantastic fit for the type of effect that I am looking for. Can you suggest other Uri effects that I should start researching?
Keybending, pencil telekinesis (That one where you balance a pen on the edge of something, and move it without touching it,) also you could do that trick where he flips a page without touching it. There's another trick where he has someone draw a picture while his back is turned and he covers his eyes, and he recreates the drawing, then, although Uri doesn't, to my knowledge, use it, the haunted key trick may work well. (For practical reasons you'll understand once you learn the tricks, the haunted key works REALLY well with the keybending trick. Hint: The haunted key is NOT bent.)
The ideal effect - I sit across from you (maybe back is turned). You think of something and draw it on a 3x5 index card. (NOTE: I always carry 3x5's with me. People know me for that fact, so it would not come across as a prop.) I then proceed to recreate the drawing that you still hold in your hand. We compare... they match! Not using this large clipboard / unique mini clipboard that I happen to carry with me. Not "Pick one of my three books, using my pad lets all come up with a page number...).
OOH, I know that one.
