As a CS person, ingenious mechanical solutions to problems like this always amaze me. If I had to solve this problem I'd probably end up with a bunch of accelerometers and gyroscopes wired up to a complicated program trying to do rotation correction. Mine would be slow, heavy, and probably not work. And then some genius would tell me about Rollerons.<p>Makes me wonder how many of the problems we solve with code could be done in other ways.
Pick up a spinning external harddrive, try rotating it, pretty phenomenal feeling when you aren't expecting it. Moving it one way causes it to pull in another direction. Disclaimer: Not responsible for damaged drives!<p>Hmm...Now I'm wondering why they didn't attach these to Felix Baumgartner!
