I really dig on the eye candy that compiz and the awn window manager brings out for Linux. Unfortunately I had to turn compiz off because java had some bugs with compiz like the unnerving blank dialog boxes in Swing based applications. Now there is a jdk early access that took care of that and so far so good. I haven't had drawbacks yet, but then again I have only played with it for 1 hour. To obtain the jdk6.0_u10 here is the link.
