Functional Lego Rubik's Cube

This Lego Rubik's Cube is a Fully functional Lego interpretation of Erno Rubik's Magic Cube. This is a very compact and comparatively strong version with the centers 4x4, edges 4x3, and corners 3x3. I used the same core as shown by Maarten Seurbaut here: http://users.skynet.be/maarten.steurbaut/Rubik_Cube.htm but I vastly improved the size of the puzzle. to build a Lego Rubik's cube makes you think very diferently about the puzzle than when you see a normal one. You get to understand the inner workings and hopefully learn some things about the geometry of a Rubik's Cube.
