1. Elegant Gnome
The Elegant GNOME theme comes with a script that installs the following: Icon theme, GTK+ theme, Cursor Theme and wallpaper.
2. Small Victory
Small Victory is a dark panel and compact (great for netbooks) version of the Victory theme - a highly customizable theme.
3. Impression / Night Impression
The update is not so recent (2-3 weeks old), but only now I've noticed the new Impression / Night Impression version.

Zuki features an amazing panel style, but you need to master The GIMP to create one for yourself.
