Xtranormal allows students to type in a script and it will automatically turn it into an animated movie . You can then set camera angles, camera changes, choose characters and even accents. It is a great tool for getting students to work with and creating dialogue or even to get them to see two points of view.
It takes a little longer to get the hang of all the available features of this program but you can still create scripted animations in minutes.
I have used this tool to create business scenarios for my students so they can analyse and interpret the needs of customers.
