Okay, people abuse the term 'holographic', but this is a pretty cool application. A company is selling a holographic grating imbedded in a glass stand as a 'holo-tv'. The idea is that a projector is setup behind and below it, and due to the nature of the holo-grating, only light comming at that angle lights (scatters, really) the grating. The effect is pretty hardcore.
