What a cool film!!! It's less than 10 minutes long, and definitely worth watching. (Not entirely appropriate for children, btw) You can view it right here:
When you're done watching the film, and aptly impressed (which I am certain you will be), be sure to check out the official site for the film: www.therewardfilm.blogspot.com. There, you can see some behind the scenes stuff like promotional art, concept art, color keys and a whole lot more!
The film was Co-Directed by Mikkel Mainz Elkjær and Kenneth Ladekjær as their Senior thesis project for The Animation Workshop, in Viborg, Denmark. You can check out their personal websites here: Mikkel's website & Kenneth's website.
You can also watch a 6 minute featurette on the making of the film right here:
