This is about the coolest thing done with an iPad since, well, the iPad itself was created. A firm named Dentsu London has used an iPad to create a series of stop motion shots assembled from sequential long exposure light paintints. They created a set of 3D graphics and then programmed the iPad to show a set of cross sections frame-by-frame of those graphics. The cross sections were "painted" into the air with long exposure photographs, and then the photographs were all put together into a stop motion animation.
The end effect is just amazing -- don't just watch the beginning on how they did it, make sure you stick aroun
