I'm seeking something with the power of the Die Cipher II but something less gimmicky. I would never walk up to someone with the DC2 because it cant be anything but something you bought at a magic store. -- DAN
I absolutely agree. That's why, when I do walkaround gigs, I work with objects that make logical sense for me as a performer of mentalism -- my business cards, borrowed coins, playing cards, and ESP cards (which are justified because they are used in "test-conditions" telepathy experiments).
For resources, I suggest first reading Corinda's 13 Steps. When you've absorbed all the material in there, you'll find tons of powerful material in Annemann's Practical Mental Effects, Ted Lesley's Paramiracles, Barrie Richardson's Theater of the Mind, Max Maven's Videomind series, and T.A. Waters' Mind, Myth & Magick.
For individually marketed effects, I recommend mine
Also, Burger's Thought Sender and Banachek's Psychokinetic Time.
