An annoying toy. Or is it a mathematical puzzle? Or is it a work of mechanical genius? Reguardless, it certainly is a neat little device.

Basically it's a cube with each side split into nine squares and painted a different color. It turns in all directions mixing up the colors. The goal is to fix it so it has one color on each face.

While most resort to pulling the stickers off and rearranging them, a select few have mastered the cube and can solve it in a minute or two.
