Voice Thread

I just came across the site Voice Thread. Basically, it allows people to comment in words or with audio about a picture or video. You can see from this picture that many people have commented on the sides of the visual image in the center which happens to be a picture that a student had drawn. http://ed.voicethread.com/#home I have not used it yet. However, I was listening to a great podcast about it today and it sounded really exciting. Check out the podcast at: http://teachersteachingteachers.org/?p=154The example to the right is at the link below:http://ed.voicethread.com/#q.b409.i3113
