Abstract:
A device comprising the following:a. a pendulum-set comprising the following:1. a crystal-set suspended by2. a thread-like member by attachment means, andb. the following electrically interconnected components:1. an electric motor such that its motor rotor is vertical,2. a light-activated current source,3. a capacitor, and4. a circuit;said pendulum-set is suspended vertically from bottom of said motor rotor by direct attachment means; when said light-activated current source is exposed to bright-light, said capacitor is repeatedly charged by means of said light-activated current source, and discharged through the windings of said electric motor by means of said circuit, to occasionally pulse rotate said motor rotor and the top of the said thread-like member to activate and sustain the rotation of said crystal-set in a smooth meandering manner about a vertical axis; whereby the said crystal-set when exposed to bright light produces a very pleasing and entertaining light display.
