@MoodleDan sent in a link last week with four free Moodle themes.
EduMoodle – a clean, blue theme with the standard Moodle icon set
Junction – this funky use of color and images will make your Moodle pop off the page.
Pretty Simple – this is one of my favorite themes which accomplishes a stark and spartan layout. Moodledan mentioned that it was created to be consistent with an existing Joomla theme that a school had already implemented;
Piranah – this theme featuring a cartoon fish might be a great template to show off a nice crisp theme with a great header image or a logo on white background.
Visit http://vl3.co.uk/moodle/ to demo or download the themes. And don’t forget to thank MoodleDan for the great aesthetics on your site if you use them.
I love the Piranah one!
