What do you get when you combine multiple PCs, projectors, and Kinect sensors? A four-foot Microsoft Cube. It’s the latest interactive art installation out of Redmond, with pulsating music and Kinect sensors that let you dance through a zany virtual portal. Microsoft’s Cube is essentially a projection system that uses 5 PCs, 5 projectors, and 4 Kinect sensors to create an interactive dance party. Unlike Microsoft’s giant touchscreens, this isn’t a product the company will be selling, it’s simply an experiment for Seattle’s Decibel music and arts festival.
