That's impressive! I spent one Christmas vacation with the inlaws memorizing all the patterns for how to solve them, but I've since forgotten most of them. I do love rubik's cubes though. So much fun. My son has the void one without a center block and it's super challenging. The patterns to solve that are much more confusing and I never quite figured it out.

Yeah, it's all about memorising patterns, which I am not good at. But that's what's crazy about my work friend though. Apparently he is also one of those who cannot visualise - he cannot "see" something or form an image in his mind. Which makes me wonder how he could have memorise the patterns...Human brain is fascinating.
