Animoto

Animoto is a web application that produces videos or slideshows from uploaded photos, video clips and music by the user. You just have to create an account, one of which is free (but limited), and then you can get started creating a slideshow. Music is one of the main aspects of your video and the slideshow is based around the music that you choose. This would be a great tool to use in the classroom when giving a presentation or putting together a "memoir" of your time together with the students, such as a senior video or fieldtrip slideshow.
