Abstract
A mirror ball comprises a pair of counter-rotating reflective hemispheres. These are each attached to rotating bevel gears that are in mesh with a horizontal static bevel gear. A vertical spindle rotates with respect to a shaft extending upwardly from a base that supports the mirror ball. The spindle has a spindle gear that is driven to rotate with respect to the shaft by an electric motor and reduction gearbox.
