Running geektool. Most of the desktops you see are running it to display computer information, weather, music, etc.
I'm also using a black dock with the icons.
See this thread for Geektool
See this link for black dock
I thought you had gotten rid of the dock but kept the apps and whatnot and just had a black strip(geektool pic probably). Didn't realize that the dock just blended in with the black strip.
