Our games are in 3D, with amazing detail at breakneck speeds on your average ATI or nVidia graphics card, (and even software render, for that matter!), so why not the desktop? I'm not much of a coder, but I do have an idea for a three-dimensional "desktop" , which could find its use in different fields (and would just be plain cool for the home and office user). For now, until things evolve a bit, your keyboard and mouse would suffice to do most tasks with the 3D environment with Hotkeys (similar to a CAD program such as Blender), and those of you who have the gaming gloves can use that to manipulate the 3D "windows" with your hands via what would look to be hand jestures (for example, if you want to move and turn a window, you just reach out and grab it, then do whatever you want, and to resize, you grab a corner and pull it out or push it in). Also, that may speed the development of holograms, but you never know.
