In this video they demonstrate a desktop interface system where the desktop is a 3d space and 'documents' (or windows) are physics effected objects that can be thrown around, stacked, organized, unorganized, folded, crumpled up, and/or enlarged. The majority of it is them working with small 'square' documents which only show the type of the file (the icon like a PDF). However, near the end of the video they start working with browser windows and images which look and 'feel' like a real stack of physical photos. The interface seems to be completely mouse based with lots of 'circle the 3d document objects' to select them and then perform a function. Probably the best one is the effect of crumpling a document or window up, throwing it in a corner, and watching it bounce around. It seems like it would be a more natural way of organizing (or at least ) accessing windows because instead of a flat surface you have a stack of off center windows where you can see a small amount of the content in each. Combine this with the top down touch screen table display for a couple days ago. Now apply the same functionality to video games or each individual website in a web browser for the win.
