Animoto, as I have said before is a great little tool for the classroom. By putting your own photos in it makes a video for you - each one is different. It now has a new feature so that you are able to put in the text to go with the graphics.
On the home page of the site you can see a sample video. Don't forget that there is an education area where you can register. This allows you free downloads. Some of my students have made these to put into their web sites or into multimedia resources.
