Tracker Ball 3D

Description

Tracker Ball 3D is based on an idea by Bram Cohen. A large central sphere gear with icosahedral symmetry meshes with four smaller sphere gears that have octahedral symmetry. The puzzle as a whole has tetrahedral symmetry. The object of the puzzle is to scramble it by randomly turning the central gear, and then solve it by getting all colors aligned again.
