Using only a single index card and an ordinary pen, you can guess or predict ANY thought; any drawing, any word, any number, any card, any shape, any color…ANYTHING!
The main effect is that a spectator visualizes an 'imagined' image on a normal index card, and the performer is instantly able to draw it. This can be presented as direct mind reading, subliminal influence, or even a prediction or open prediction.
Here are some points to get your gears turning:
-The performer can reveal the thought to the audience before the participant ever says anything out loud
-Nothing is ever written down by the participant
-No extra index cards are used or switched in
-No Fishing or Anagrams
-No Peeking
-No Pre-Show
-No Stooging or Instant Stooging
-No Dual Reality
-No Gimmicks
