I just finished compiling it on my machine... Here are a few screenshots:

The last one is with KDE4 at idle (effects enabled, but only the framerate one actually activated), and has top running in an xterm. I have no had a chance to play with plasmoids yet.
This is with an X1900 and the open source radeon driver built from git.
EDIT: If you tried to get to the screenshots, and couldn't, please try again. We had a power outage and I don't have apache start up by default when the system comes up, so I had to restart it when I got home.
