So here's my nerdiest hobby: cubing. When I was a little kid, everybody wanted a Rubik's cube. I begged my dad for one, he bought me one eventually, and, like just about every other kid in the early 80's, I had no idea how to get anywhere with it. Fast-forward to adult life. I was at a convention, and they were giving away magic cubes with company logos on them as a marketing trinket. I picked one up and actually started to try my hand at developing an algorithm-based solution. A week later, I had something very basic, but I could do it. For the next year or so, I was all about analysis of the stupid puzzle, trying to learn something new, and I eventually worked out an intermediate-level solution for it. I was pretty proud of myself, since no one else seemed to have really developed anything in between solving for the first time and competitive speed solving. But, thinking objectively, other than for pedagogy, my solution really serves no practical purpose. Anybody else into cubing? I'm pretty darn casual about it. I recently got ahold of a couple Dayan Zhanchi stickerless. Makes my old freebie cubes feel like something from the stone age. The other thing is that switching between playing guitar and twisty puzzles seems to be a little straining on the wrist. IDK if anybody else here has ever really spent a considerable amount of time with a twisty puzzle, but I'd be interested in hearing whether the problem is unique to me or not.
