Brought to you by the Moodleman Blog, The Moodle Playpen is a demonstration Moodle site that allows users to explore Moodle’s possiblities. There are demos of standard features, advanced features, layout examples and discussions.
This site has been around for awhile and is maintained by Julian Ridden (follow him on Twitter!). Whether you’re looking for a new look or a way to spice up the functionality of your Moodle site, The Moodle Playpen is a great place to get ideas for your own Moodle site. One of my favorite demos is the Accordion Course Format layout! Check out The Moodle Playpen for more ideas!
