If the only thing holding you back making masses of gorgeous people pulsate to the beat is a lack of hardware, it's time to check out AirJ, said to be hitting the App Store soon. How exactly it works is something of a mystery at this point, but you can tell from the video streaming below that the idea is to do for DJing what the Air Guitar Rocker
did for real strumming. It looks like you might need two iPhones
to make this magic happen, but that's still cheaper than a set of Technics -- though whether or not you'll still need actual
technique remains to be seen.
