    Well, lasers work in free air. Look at all the light shows at concerts and the like so I guess it is technically possible. I have to ask why though when you look at that site.

    OOh, yes please. I want a virtual globe spinning above my desktop that I can 'grab'.

    They are kack!! I have worked on several ways to achieve this effect and the resolution is awful. A major collaboration between DERA and Ford have a very good display but limited by pure computer processing power as pixel counts are well into the billions!!

    One day...

    It's a variation on the "projecting on to a fog screen" idea. No physical screen, but instead it generates a cloud of mist that acts as a reflective surface for the projected image.

    This type of technology has a couple of limitations at the moment. The first is the very tight viewing angle. As you go more off axis the brightness drops away and the image becomes more blurred. The other issue is how to generate and control a mist screen so that it's big enough for a decent sized image without making the room feel like you're trapped in a 1950's London smog.

    It's an interesting idea but its got some way to go before it becomes commercially actractive for home use.
