tried and failed to bring a 3D desktop interface to an otherwise 2D operating system, but that certainly hasn't stopped others from trying. The latest example to crop up comes courtesy of none other than Microsoft, which recently received a patent for what it describes as a "method and apparatus for providing a three-dimensional task gallery computer interface." In other words, it's an interface intended to help you better manage multiple tasks, which the patent suggests could be done in a 3D environment with a floor, walls and a ceiling. Apparently, you'd be able to group multiple windows at various spots in the "room," which would let you rely on your spatial memory to easily find a given task -- with the room getting deeper and deeper to accommodate more tasks. In the patent's claims, the only means described for navigating around that room is a set of icons that would adjust to suit the 3D environment, although it certainly seems like it could easily be adapted to accommodate gesture controls as well.
