My personal theme. Kind of dark and purplish. I started with Cimi's MurrinaLoveGray, changed the colors to be like CleanIce-Dark, then tweaked the Murrine Engine settings using the configurator.
I am using the Just4fun xfwm4 theme in the screenshot to complete the picture.
Requires Cimi's GTK2 Murrine Engine, version 0.51.
