Does the shape of a Rubik's Cube affect how hard it is to solve? At first glance you'd assume the irregularly-shaped pieces of this R2-D2 rotating puzzle would make it easy to put back together, but before you know it, you could have a real mess of droid parts on your hands.
For around $34 (though you might have to import it at a premium of $79 excluding shipping from sites like Japan Trend Shop) you can spend hours frustratingly trying to put the little droid back together after a friend messes it all up. And with this Rubik's Cube swapping around a few stickers to cheat your way to a solution just isn't an option. [HobbyLink Japan via 7Gadgets]
