The folks at BERG and Dentsu are exploring screening surfaces and playing with the popular 'glowing rectangles' that inhabit our world. They invented a new photographic/stop-animation technique for making media. Software models of 3-dimensional typography, objects and animations are created and cross sections of the models are rendered like a virtual CAT scan to create a series of sliced outlines. Those are played back as movies on the surface of an iPad and extrude 3-d light forms as the iPad moves through space. That movement is recorded through long exposures (multiple exposures in composite to create a film like the one above). More on the method here.
