The Gear-cube was a brand new concept in cube design when Oskar van Deventer was inspired by a gearing idea by Bram Cohen to create it a few years ago. The puzzle uses a full gear mechanism that requires twelve turns to complete one rotation. The gears are placed externally so that their orientation can be seen, adding gear teeth to the corner and edge pieces and using a new speed cube inner core. All in all it adds up to a completely new and unexpected solving experience even though its still considered by the inventors to be still easier than the original Rubiks Cube. These steps result in a twisty puzzle that on the one hand has some of the features and attractiveness of the original Rubiks Cube.
