The inspiration for their display was pulled from someone's ass. Seriously. There was an article discussing it a while back. There is a new kind of colonoscopy camera that uses a fiber optic cable with a rapidly-spinning business end to build up images rather than a camera with a conventional lens. You can imagine the impetus for shrinking the probe. They "just" reversed the light flow and now they have a fiber optic projector!
