From Hitachi, a new imaging system called the AirSho that lets you project images onto specially coated Plexiglas so that they appear to just be floating in air:
The system displays full-motion images – generated by a PC or DVD player – that give the illusion of appearing out of nowhere. It uses a floor- or ceiling-mounted projector that shines video onto a photopolymer-resinous Plexiglas display. The 40- or 60-inch diagonal screen sticks to the window’s surface with water – like a decal. “It’s similar to a screen, but you can actually see right through it while an image is appearing,” says Ray Soltys, a spokesman for Hitachi America’s Digital Media Division.
