Hi, I know it is minimalistic, but perfect for long working day ;)
I used to place the icons at right side of the screen because I find it more intuitive this way, as I am right-handed.
WM: xfce4 with idesk to display icons
I don't run KDE but I find kde-org is a nice place to share GPL graphics and this wallpaper can be used by KDE users as well
Feel free to comment...
