The LanLan 3x3 Geary Cube resembles an ordinary 3x3 on the outside, but it actually has as complete gear cube mechanism inside the cube. When one layer is turned, the gears inside the cube are rotated, causing other layers to turn as well. The puzzle was produced by LanLan and designed by Oskar van Deventer. It features an official Oskar logo.

Product: LanLan 3x3 Geary Cube
When the original design for the Gear Cube was called the "Caution Cube", then I guess this variation on the concept was in order. Ib all honesty though, I really love this puzzle. The turning is not as great as Meffert's Gear Ball, but not as tight as the original Gear Cube. The gear mechanism is completely hidden, even mid-turn, and the only thing giving this puzzle away are the stickers, which I have since replaced. The puzzle even corner-cuts a little bit, which is impressive considering the mechanism that's hidden underneath the surface. One problem I have faced with this puzzle though, is that layers, if applied with enough force, can be forced to turn independently. Other than that I have had nothing but great experiences with this puzzle
