Massive Selector: SmithsonMartin’s 42-Inch Touchscreen DJ System. [Wired.com] - Looking like something lifted from the nightclub in Tron: Legacy, The Emulator DVS is a giant dashboard for selecting and mixing tracks. Position the included 2,300-lumen projector on the shelf beneath the 42-inch infrared touchscreen and hook up a laptop and the audience can watch as you swipe, twist, and tap to keep the beats bumping. Bring your credit card, though. It’ll set you back more than five grand.
