I found this on Boing Boing Blog (which I enjoy but can't keep up with--they're so prolific!). I thought it was so nice--a perfect little video for a weekend, which I hope will not be quite so hot as the week!
They quote the filmaker, Joaquin Baldwin:
"This film was inspired while driving back from a trip to Palm Springs, when my partner said that it must take them forever to plant and grow so many windmills. I wrote down the title The Windmill Farmer for an idea to explore later, and about a year later I started developing it into a character and story. This film took 4 months to complete from the first boards until the final mix"
