A year ago I created this comic strip, depicting a model for networked learning and open courses. Originally I had the comic in a PDF for a 15 minute presentation (can you believe that!) at a conference in Sydney.
I just found the images again and have loaded them to flickr as the OpenCourseWare set.
I still like them now as much as then :) I'll have some audio to go with it soon.
