Phoronix has made a bunch of pictures of the latest alpha of Ubuntu running XGL Compiz
The show is here
And on Tuxmachines they have a description accompanying the screenshots.
The plug-ins utilized were cube, decoration, fade, minimize, move, place, resize, rotate, scale, switcher, wobbly, and zoom. Unfortunately, the Gconf Compiz abilities were not accessible from the Dapper Drake repositories during our testing time. At hand today are a wealth of images demonstrating the various graphical abilities, as well as a few looks at the newly introduced Ubuntu Espresso LiveCD installer. Keep in mind, the Compiz Wobbly shots are quite aliased, thus we are working on an animated preview by the time Xgl + Compiz is largely introduced to Linux.
