Thank you Christoph.
To the other responders: you obviously didn't look at the video it is a demonstration of a user moving windows that are transparent, and fluid like , ie if you grab the top of a window and move it sideways, the bottom will drag like it was a piece of cloth. Even a window playing a movie. When switching between desktops it is like the desktops are the faces of a cube and the cube is spun sideways, up and down to display the other desktops, all very neat and not very corporate, and not even very useful per se, but I can't wait to try to get Xgl working on my Beta 3 box.
It will be so funny when Microsoft Vista finally ships, and it will look like last generation of desktops next to Linux and the Mac.
Since NLD10 and 10.1 share the same codebase, you likely will see parts of it. Problem is that 10.1 will be ready way earlier than NLD10, so it might not be integrated yet. Ciao, Marcus
