This is one of my favorites animated shorts. I love the whole thing, concept, designs, animation, lighting, etc.
I am honored to have met one of the creators and director of this short, Tim Watts, who's one of the animators on the show I am working at the moment here at Dreamworks.
It was animated twice, one in hand drawn and the final in stop motion which you can see below.
I am sure you will enjoy this as much as I did. It is brilliant.
