Anybody but me do Rubiks cubes for fun? I learned to do the 3x3x3 about 3 months ago. I can do it in about a minute. (That's actually kind of slow.) I just bought a 4x4x4 cube, and the transition was super easy. I only needed to know 6 more moves, two of which are super easy. Now I'm going to buy a 5x5x5 off of eBay. So, anybody but me think they're interesting. Also, anybody have a 5x5x5 or 6x6x6 they'd be willing to give up?
