Project Looking Glass is based on Java technology and explores bringing a richer user experience to the desktop and applications via 3D windowing and visualization capabilities. It is an open development project based on and evolved from Sun Microsystems' advanced technology project. It will support running unmodified existing applications in a 3D space, as well as APIs for 3D window manager and application development. At the moment, existing application integration is supported for Linux platforms.
This is what the page says. In my point of view it will take a wile for this to work the right way. I'm no Java developer so I'll keep my consideration at this comment. The visual of this WindowManager is just too cool. The concept of rotating applications windows are just what it was supposed to be.
