AirJ app threatens to make decks and drum machines obsolete, but only if you look this serious (video)
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.
