Abstract
Abstract The display system includes a crystal ball having an operating circuit coupled thereto which includes electrode means in operative relation with the crystal ball and adapted to be energized by proximity or contact with the hands of an operator, whereby the associated circuit is energized and provides a desired response including, as an example, sequencing of lights. The circuit includes an amplifier operated by the electrode means connected (1) to means for energizing the lights and (2) to a multivibrator and flip-flop for sequencing the lights. The circuit includes a capacitor for storing charge and holding on one light after the operator removes his hands from the apparatus.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
160 words
A crystal ball a pair of contact chains disposed beneath said crystal ball and adapted to be contacted by the hands of the user to short said chains together, a series of electrically operated lights, first transistor means coupled to said chains and adapted to be turned on when said chains are shorted together, second transistor means coupled to said first transistor means and adapted to be turned on thereby to energize said series of lights, a multivibrator also coupled to said first transistor means and adapted to be turned on thereby, a flip-flop coupled between said multivibrator and said series of lights and adapted to turn each light on in turn and in series, and capacitor means in said circuit which is charged when said first transistor means turns on, said capacitor holding on one light for a period of time when said first power means is turned off, said one light then remaining visible through said crystal ball.
