There’s a great new theme at Moodle.org called “Gekko” which was developed by Colin Wheelhouse for the Bungay School Moodle: http://bungay.moodle.overnetdata.com/.
The theme has a great green color scheme with some of the Aardvark theme components (specifically the user profile picture on display) and a customizable drop down menus. It’s available now for download at http://moodle.org/mod/data/view.php?d=26&rid=4367
I had zero installation/formatting issues on my own site: http://www.joedle.com/. Now just to tweak the menus, logo and colors.
