NOTE: AERIE WILL NOT WORK PROPERLY IN MOODLE 2.3! We are waiting for some changes to Moodle core code. In the meantime, there is a version for 2.3 called Aerie Lite, which is downloadable from Github. Aerie Lite does NOT contain the custom block regions, sorry!
Aerie is a fluid-width, three-column theme for Moodle 2.2, with six extra positions for blocks (three top and three bottom). The custom menu contains a Home link which always appears to the very left, and a My courses and Login/Logout link, which appears after any administrator-added items.
Aerie has a settings page that lets you modify various background colours, custom footer, custom css, and the site logo.
NB: While the theme is for Moodle 2.2, the version.php file contains the information for lowering this requirement. Theme has not been tested in 2.0 or 2.1, so doing so is currently at your own risk. My aim is to have this theme fully compatible with all versions of Moodle 2.
