Spherigears combines the ideas of the Sphere Gear puzzle (a mechanical maze puzzle by Oskar) and Bramboules. The combination was suggested by Bram Cohen. Spherigears has four spherical gears that each rotate with three degrees of freedom. The cage can be folded open in two ways, such that the spherical gears mesh in pairs, either AB-CD or AD-BC. After scrambling, the object of the puzzle is to get all spheres back to their original orientation.
