I'm using a 3d desktop with cool eye candy effects based on Beryl for some thime now. Now I have also installed kiba-dock, which is a start bar similiar to the dock of Mac OS X with an own physics engine.

I recorded a video of this desktop (download, XviD, 17,5 MB). I'm sorry that it is not very smooth, but the parallel video recording used up much resources. But without the video recording everything runs smoothly.

Moreover you will find two screen shots of the desktop in my gallery: Desktop and Desktop 2.
