My Paper Mind is a fantastic short film by Javan Ivy. It is made with an experimental animation technique he called "Stratastencil," where stacks of differentially cut paper are used as "frames" in the film. The 30 or so second animation above took about 18 hours to make.

I used to do origami but I always got annoyed with the tiny folds and did it too fast. My cranes always just looked like a scrunched up bit of paper...
Not long and full of itself. Very nice.
