Eye Candy on Ubuntu

I have installed on my cusin's computer (another Ubuntu fanatic) Compiz/Beryl with Xgl on a nVidia card.
It is incredioble how nice it works. Th gui is quite fast and responsive the graphical efects are awsome (wobbling, zooming).
The instalation was a little odd but afterwards everything went smooth (only a few crashes - but that's normal for such tools that are very new).
