I luv desktop screenshots! So I wish all a Merry X-mas and Happy New Year!
FYI the wallpaper from customize.org called snow falling. Running Ubuntu Gnome of course. Theme Dust with Icons LaGaDesk_BlackWhite_III from gnome-look.org.
You might notice only using a bottom panel. It works for me. To me less is more. It’s not showed but using gnome-do makes this work. It makes programs come up quickly. The second screenshot you might notice Lady GaGa doing her stuff. The last is a little 3d effect of two workstation. After checking out compiz and the cube, I use simple effects for every day use.
