Today I thought of making a screenshot of my current desktop. So, here it is.
Some useful details:
* kubuntu 11.10, KDE 4.7.4
* wallpaper: Glaze from Caledonia Official Wallpapers
* KDE interface and window decorations style: Oxygen, of course
* color scheme: Caledonia Color Scheme
* icons: Caledonia Icons
* fonts: mainly Ubuntu font
* Plasma theme: G-Remix (Helium One)
* task manager: Icon-Only Task Manager (Icon Tasks)
Not visible in the screenshot but also useful, I hope:
* mouse pointer theme: DMZ
* splash screen theme: Caledonia
* Plymouth theme: Caledonia
As you can see, I'm a big fan of Caledonia themes :)
I also have them installed for Amarok, Gimp and LibreOffice splash screens.
