Konica Minolta developed a new display and is looking for possible applications. The technology sounds nice:

The Holographic See-Through Browser prototype resembles a pair of eyeglasses and uses a prism with a thickness of 3.5 millimeters and a holographic element to reduce the weight of the display to 27 grams.

One use I can imagine - a men (or woman) with a hoover doing this:
how a user could watch a motorcycle race on the display while walking around their house.

The other idea I await for years is real 3D-game feeling...
