For most people, there is only one name that matters in the world of Microsoft Surface / "rave" integration. And that name? Al Roker. But that hasn't stopped the company from continuing to develop new and innovative ways to show off its super-sized touchscreen device in the milieu of clubland. VPlay, for instance, is a live video mixing tool that allows one to display video clips and live images, manipulate effects, and concoct some pretty complex signal paths with your bare hands. Interested in giving this one a spin? No word yet on a commercial release, but do make sure you peep the video after the break.
