If, like me, you found the best way to solve the Rubiks cube was by prising off a corner, best read no further.

The latest craze (?) is to attempt to solve a 4D version of the famous puzzle.

Basically a bunch of mathematicians and programmers have got together (always a bad sign) and come up with a computer sim (Windows and Linux) which lets you try to solve the 4D version.

Apparently there are more permutations than there are atoms in the universe. Despite these extra possibilities, the 4D cube is said to be not much more complex then the 3D version for those that mastered it.

I don’t know about that: assuming I could prise a corner off a 4D cube, I reckon there would definitely be bits left over afterwards!
