oh isn't that kind of old?? i heard of that back in early 2001, but they banned the website and i see it's back now. a friend of mine who's good with computers made a motion simulator that was not so different from this - you had to put ur finger in one end of the machine and the other end would sort of make a simiar but intensified motion.
i wonder if he ever got rich selling it around campus.
btw, y'all know there are many tremek citizens who would be happy if they had a group buy sale
