Screenr - Your own screencasts for free!

I came across this app just recently and I think it's fantastic. I've been using PodOmatic to create short podcasts for my trainees with guidance for assignments and planning, etc. and although the podcasts are great and very useful, I think this app has a little bit more to offer - the visual element. Why not give it a try? I think it's really good not only for teacher training but for teaching in general. Students/trainees can be at both sides of the table: they can create their own screencasts or watch the ones you prepare to help them with their own leanring and studying!

What I like most is that you don't have to download anything and it is FREE! What else do you want?
