Source: *www.macrumors.com/2008/12/11/apple-exploring-3d-desktop-and-application-interfaces/Dozens of Apple patent applications were published today revealing research that Apple had done in 2007 on many topics encompassing future versions of Mac OS X. The most intriguing is a series of patent applications which describe a "Multidimensional" user interface. Apple has essentially been working on true 3D desktop environments. Disclosed herein are systems, aparatus and methods, including a multidimensional desktop graphical user interface.
In one titled Multidimensional Desktop, Apple includes a number of diagrams depicting what such a desktop might look like and how it would work.

Along the side are a number of three-dimensional "function" icons that may trigger certain commands on each surface. These icons can be manipulated in 3D with a physics model so the icons can appropriately "fall" if displaced.

...Apple has not been the only one working on 3D desktops. One popular YouTube video demos a 3D desktop in action. Sun's Project Looking Glass also demonstrates a currently functional 3D desktop for linux and Solaris x86.
, I was one of the few luck ones to see the demo from microsoft itself 
, they did admit it was a major failure
