I've reinstalled Debian, for no particular reason (the only difference is that this is 64-bit). Here's a shot of it.
Debian 7 & Xfce 4.8
GTK & Xfwm: Zukitwo
(an older version which supports GTK 3.4, downloaded from the Webupd8 themes repo); panel background from Soothe
Wallpaper: Half Awake from fiftyfootshadows
Applications: Thunar, urxvt, weechat
Font: Droid Sans
Bottom panel autohides, and the systray is in the bottom right corner (Gnome Shell style) on a third panel, completely transparent and autohidden.
