Mary Evans, a contributor of many great themes to the Moodle.org theme repository just posted a screenshot (below) of her adaptation of Aardvark to be compatible with Moodle 2.0.
Check out another of Mary’s themes called Premium.
Aardvark is a great theme for Moodle 1.9, including custom menus and a insert of the student/user’s profile picture in the top right. For more flavors of Aardvark visit the theme repository: http://moodle.org/mod/data/view.php?d=26.
Download this for Moodle 2.0 at http://moodle.org/mod/data/view.php?d=26&rid=4357
