The creative cats and kittens at Obscura Digital have put together a stunning piece of performance art / data manipulation demo which combines their proprietary multi-touch software with Musion's Eyeliner 3D holographic projection system. Like that BMW installation we saw recently, this is one of those odd combinations of technology and art which is best seen in action rather than described -- so check out the video after the break and see the work in all its mind-bending glory.
