Linking to this post too, since anonymous has stickied this thread as part of Statler Tips and Tricks (thanks for that!). Different wallpapers for each desktop via the Compiz Wallpaper plugin...
@Unia, funny you should ask. I was just looking at that screenshot yesterday and thought to myself... "Did I post a Gnome screenshot by mistake?" I' wondered because of the folder icons in Thunar, which currently doesn't properly use user-dirs.dirs to set custom folder icons, you have to attach emblems to them. Looking closer, I think I was testing Nautilus Elementary on Xfce.
Anyway, it's all in the tutorial, but to save you the trouble the GTK+ and icons are Shiki-wise/Gnome-wise. If you run Debian...
sudo apt-get install shiki-wise-theme
The Emerald theme is komar-blue with the engine switched to truglass in the Emerald Theme Manager...
