Spotted on eBay: this 80-inch widescreen whose custom cut glass is able to capture light at a certain angle, making images appear to hover in the air when paired up with its included Sanyo LCD HDTV projector. So it's basically a rear projector whose screen is made of glass and hangs out there in the open for all to see.
Don't be fooled by the bandying about of the term "holographic," because there's not really any 3D going on here. It's just a cool-looking cut-glass screen, a bit bigger than its predecessor, the Claro Holographic Television that was on sale at Harrods London for 15,000 a couple of years ago. Buyer beware, starting bid is 5500 (about $10,427).
