I found glogs today, and then I found edu glogs.
Glogster provides an online poster creator, which enables video and audio to be added to the poster. There is a gallery of graphics available, but users can upload their own images and media. Users can record video and audio directly at the site.
Glogster also offers EDU glogs and has a few examples of student work. I threw this one together so I could try it out -- ideas for edu glogs | Glogster
