Within their book commercial, each student had to identify a major theme from the book and provide a brief character and plot introduction. We used the educational version of Animoto and created students accounts so they would have the abilty to create longer vidoes. The process to setup the accounts was slightly cumbersome but the results were very impressive.
Here are a few examples: The Lord of the Flies, The Fault in Our Stars, Fahrenheit 451, and Sleeping Freshmen Never Lie.
