Are you moonlighting as a musician? Maybe training to be a massage therapist in your part time? Or maybe you're just really, really bored. I never got the whole Dance Dance Revolution thing, but if you can't get enough of dancing on pads, now you can do it with your fingers on the USB Finger Dance Mat from Drinkstuff. Plug it in to one of the spare USB ports everyone seems to have these days, then follow the lights with your fingers. I'm sure it's a lot of good mindless fun, right up there with solitaire and Free Cell.
