Detsu London has an interesting video up on Vimeo where they combine long-exposure “light painting” with 3D Modeling and an iPad to create text and models floating in space, then use those images in a stop-motion movie of robots and text flying around us.
We use photographic and animation techniques that were developed to draw moving 3-dimensional typography and objects with an iPad. In dark environments, we play movies on the surface of the iPad that extrude 3-d light forms as they move through the exposure. Multiple exposures with slightly different movies make up the stop-frame animation.
Several people are calling this an “iPad Hologram”, which is inaccurate. It’s a clever combination of catchy words, but this is more realistically something like stop-motion light-painting, similar to the Sprint Flashlight commercials, but using an iPad.
