I just recorded a (very) quick and dirty screencast to demo the EduGlu sandbox prototype that was put together in Drupal. It's a 23 minute session, and clocks in at 28 MB. I probably rambled a bit more than I should have, but you'll get the idea...
(The Anarchy Media Player displays a smallish video embedded on this post, but you can download the video to view at 640x480 if you want to try to read the tiny text in the screencast)
