Thinking Moodle Theme Design
*New - Added keyboard navigation the website. Use your arrow keys in gallery to navigate fast and use Shift+1, Shift+2 and so on for menu links on the website(Not on Moodle). To use keyboard shortcuts in your Moodle themes, press Ctrl+Shift+K to see your list of Admin keyboard shortcuts. Watch out this space, Moodle UI is gonna get richer in interaction!!
*New - Added support for New Layout in themes!
*New - Added Moodle Bar for easy navigation.
*New - Added Menu Builder so that you can create your menu items without having to write a single line of code.
Finally I discivered Hayley eLearning Center, have nice looking page of free themes that covering Moodle 1.9 and Moodle 2.0. I particularly liked the way in which the themes on this site have taken on customisation of menu options and colour styles
