Watch How an iPad Was Used to Paint This Stunning Hologram

This video shows, without a doubt, the most magical thing I've seen the iPad do yet: creating a series of gorgeous, twinkling holograms, captured with long exposure photography as the iPad was moved through the air. Confused? Just watch.

The video is a collaboration between Dentsu London and BERG, the latter of which is responsible for awesome projects such as BBC Dimensions and the Mag+ tablet concept.

Of this latest feat, they explain:

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.
When the individual words are writhing across the screen there's barely a trace of the iPad that made them. But my favorites are the final shots, where all three words appear together and you can see the ghostly forms of the people that are moving around the space to create them. Kinda spooky, very beautiful. [BERG and Dentsu London]
