Hi Twisty Puzzles fans,

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.

Watch the YouTube video of the current, much improved version.
Buy the puzzle at my Shapeways Shop.

Very nice, and reminds me of half of a Gear Shift.

Very cool. I would think something like this could easily be used in something that accomplishes something other than a mechanical puzzle. There's got to be some other application.

Not sure why, but DLitwin's comment reminded me of this thing. https://www.youtube.com/watch?v=79zWwLGqsFE

Could you make a version of that with Spherigears inside?

Yes, but I won't. Not only does the flexibility of the nylon allow cheating in the current design. Also the alignment of the sphere gears is rather cumbersome.
