Rubik's Cube

The Rubik's Cube is a 3-dimensional combination puzzle invented by Erno Rubik in 1974. The goal is to turn the six faces in certain combinations so that each face is one solid color. With enough practice and memorization of the sets of moves you need to learn (called algorithms), you can solve it in under 30 seconds. I may have taken it too far and cut my times down to almost 18 seconds.
