Forget about any type of bussiness app, I can see myself browsing the complete internet with this type of interface. (isn't that what Tom Cruise did in Minority Report? Lookup information in some sort of document style app? Can't remember myself)
Mapping sites, pages and links into 3D space
Being able to move them around and manipulate each page as a window on the screen.
Now that would be a killer app; a 3D browser with this interface.
Andy: question? When looking at the video, the camera images seem to have some sort of 3D effect. I would assume that with goggles, real 3D could be achieved.
Is there any thinking going on about that? (I did not yet read the paper)
