I ran across this video last night while going through my Dj blogs, it is a special touch screen / projection setup using this program called Emulator that runs through other programs like Traktor / Virtual Dj, Ableton etc…
The normal setup of one of these puppies is using a touchscreen PC like the HP Tabet laptop, which has a 180 degree rotating touch screen, from what I gathered from the description the dude has his own touch screen linked to this called Töken, which should have its own site soon. For more on this program hit up their site.

There will be more postings about news in the Dj world including reviews of products…Cheers
