Dentsu London and Berg create an amazing animation using the Apple gadget.
A recent collaboration between Dentsu London and design consultancy BERG resulted in the iPad being used for painting a series of stunning holograms. The iPad light painting technique uses stop motion photography to record the device moving through space which produces 3D forms in light.
BERG explains their technique:
First we create software models of three-dimensional typography, objects and animations. We render cross sections of these models, like a virtual CAT scan, making a series of outlines of slices of each form. We play these back on the surface of the iPad as movies, and drag the iPad through the air to extrude shapes captured in long exposure photographs. Each 3D form is itself a single frame of a 3D animation, so each long exposure still is only a single image in a composite stop frame animation.
