Rubik's Cubes

If you know me, you probably know I'm a big fan of Rubik's cubes. That's my excuse for featuring two awesome cube solving robots on LMOTD just two weeks apart.

While finding links to round out those posts, I found out that my collection is incomplete. First of all, this section of Wikipedia actually exists - which is exciting in more ways than I should think about. I apparently need to get my hands on 5x5x5, 6x6x6, and 7x7x7 cubes ASAP!
