So many of you asked me if Powtoon is another good tool to use. Here are two examples from my daughter Jacquelyn. She found this tool last year on her own and decided to create her French project with it.
She had a lot of fun with it, you can also download a transcript of the video.
I have just signed up the free account, so I know it is still available. The free code is on my second image. Definitely worth it to check it out! Here is the direct link to Powtoon promotion: http://www.powtoon.com/lp/toonup/
