Yeah, another of *those* tutorials. If you use Ubuntu 7.10, and you want those wobbly windows and Avant, read on and get a shiny, bling-filled desktop with convenient controls to turn everything on and off.
Read it here
Use the bling-on.sh file to turn on Compiz, then Avant. Compiz has to be running, or Avant will look all ugly. bling-off.sh turns them off and runs Metacity (GNOME's default window manager) in Compiz's place. Running either of them will keep all your windows intact.
The last step should be pretty easy: Annoy the hell out of anyone who uses Windows Vista.
