AnMish is new (beta) site that I found out about from Cliotech and is great for digital storytelling. Not only is this site super fun and easy to use but it allows users to select characters and then record their own voice to add to them. A person can then embed videos to share w/ others. This site does have cartoon celebrities, puppets, and more to choose from, while not ideal for education it can be used by a teacher or w/ proper supervision.
