This studio based in Seattle has a site that’s almost like a desktop OS, in that the different areas of the site are in their own draggable windows, over a hi-res photographic background that you can change. You can even drag the windows into a Dock-like thing at the bottom of the screen, where they shrink to thumbnail size. It seems to me that this idea is done quite well, but a bit of overkill for the amount of content.
