Calibrate by Joel Dickinson

A participant draws an image and the performer not only identifies the image but also his participants star sign.
A participant imagines a person with an object, the magician not only divines the person and the object but also his participants star sign.
Strike Two : This is a bonus principle which will help you reveal you participants star sign.

Calibrate is a real time star sign reveal and is ideal for walkabout and stage performers.
