A while back I wrote about a cool display technology I saw on ABC News, where an image floated on a piece of clear glass. Later, I saw this being used at Harrods in London in a clothing display. And now, you can buy one for your home.
The projection system is actually a revolutionary holographic film which displays any image fed through a projector at a specific angle onto a transparent display. The clever part is that all other light is ignored, which should result is a remarkably bright and sharp 40-inch image – even in brightly lit environments. The screen is a mere 1.5×1.0m rectangle of 10mm glass with a 610x814mm sheet of translucent film attached to it, giving the impression that the image is suspended in mid-air.
