Animoto is a web 2.0 tool that allows you to make videos. Animoto is kind of like iMovies but it is much faster to make a movie. For example, if you go on a field trip in the morning, you can have a movie to show the students in the afternoon. You can also create videos from your iPhone by downloading the app.
Check out the video I created a while back so you can get a feel for Animoto.
