Let's imagine just some of the effects that are possible with VERTIGO:
A card, freely chosen by a spectator, coincides with the prediction made by the performer some seconds before. No forcing of cards. As simple as that: the spectator names the card and it is the same mentioned in the magician's prediction.
Imagine a roulette: the spectator chooses any number, and it coincides with the number the magician predicted. The spectator chooses a character, a country and a letter (or something of any other category) and there is an astounding full coincidence with the magician predictions.
You will find many more ideas that will astonish your audience.
VERTIGO is a genius tool, not only useful in mentalism, but also for parlor, stage or close up magic.
