Just your typical clearlooks theme made dark/black'ish with a 24px panel background gradient.
To make the panel look like that set it to 24px and then:
Right Click -> Properties -> background -> select BlackT3.png from the tar.gz
Then open Gnome Color Chooser and click on Panel:
Normal: fg=#CBCBCB, bg=#464646
Hover: fg=$FFFFFF, bg=$464646
Hover Selected: fg=$FFFFFF, bg=$464646
Alt Selected: fg=$FFFFFF, bg=$464646
Font: Myriad Pro Semibold 8
Sorry, I don't know how to make any of that automagic.
