I finally came up with a UI that I like. I don't have any special decorations (my system can't handle much more than what I have!), but it's functional, and I hate having any part of the screen blacked out for no reason.

I use Bongos, FuBar, xPerl and Quartz for the interface changes.
and btw, Horde sucks at Eye of the Storm! =D
