We've all seen these Rubik's Cubes practically since they came on the market.
There have even been all kinds of robots that are able to solve a mixed up cube but...

What about a cube that can solve itself unaided?!!

Yes... it kind of takes all the fun out of it now doesn't it?

Well, here it is...

Hehe, cool 

Such a clever invention the Rubik's cube. I still have mine which was bought when they were first around in the 80s.
