U.K. advertising agency Dentsu used iPads and cutting-edge graphics tools to create 3-D light images promoting their creative philosophy, "Making Future Magic." Using stop-motion animation and light painting, Dentsu and British designers Berg created an image of what "magical visions" of the media might look like. Watch them explain their technical process, then look in awe at the finished product. There are more still images on Dentsu's Flickr feed.
