Cubed

I was looking for Sipser's Introduction to the Theory of Computation, when I just got helplessly stuck to this cube. It was this time last year that I was buying one of these. Or was it the year before? Funny how time flies.

I still can't solve it though. I seem to vaguely remember being able to do this back when I was only a kid. But now I can only do one side, with the centers of the other sides aligned correctly. And I don't want to to use the cheat sheet to learn how to do the rest. Which probably means that I will never be able to solve the whole thing.

Ah well. Story of my life.
