A Kicker background with a black bar or black glass feeling. Use blackxxx-t.png when Kicker is placed in upper position (like I have)
I've done the same background for Kooldock (only Blackbar, I use BG-Kore with Blackglass) and Kwin. Also a colour-schemes that's goes nice with these bars (all included).
