This is Overglossed GTK theme, LaGaDesk BlueNight icon theme, GKrellM CopelandOS theme and a slightly tweaked Smarald Emerald theme. All of the credit for this goes to the original designers of these pieces. The only thing I made was the Raid drive icon which was just three LaGaDesk drive icons stacked.

*Edit*

Added Gnomenu and updated screenshots. If you dont see the motorcycle background for the very first image then refresh your window and it will load the correct screenshot.

Thanks for looking.
