On a weird impulse I recently picked up a Rubik's Cube, deciding it might be fun
to finally learn how to do one, especially since it seems to emphasize some sort
of thinking my brain doesn't really do. It was pretty easy to learn the first
half of what's apparently the simplest solution, but to master the end of it
would require memorizing a few slightly complex formulas, so that will be a
challenge. I'm not sure I'll actually be willing to memorize enough of what you
need to to work this, but I do feel it would almost be worth it for the
possibility that I would come across one someday and casually solve it to that
amazement of the admiring crowd. I guess it is proof of geekdom that this is
what I think would be impressive, as opposed to, say, dunking a basketball.
