A variation of Oskar van Deventer's gear puzzle range is the Gear Ball. With similar mechanism to the Gear Cube manufacturer Mefferts says this is the smoothest turning puzzle they've made ever! It's also an amazing looking piece of puzzle art.
As the gears move, the colors change on each facing as well as the black frame. Once you've messed it up the challenge start to return each side to a solid colour just like the Rubik's Cube and other well known twisty puzzles.
The puzzle even has a hanger so it can double as a valuable and unique Christmas tree ornament.
