349, by filmmaker and artist Kristen Lauth Shaeffer, uses stop-motion animation to create a choreographed dance out of diverse, hand-drawn frames. Over the course of two years more than 300 individuals designed and decorated slides pulled from a filmed dance performance, each lending their own style and energy to their specific drawing. For the frames, the participants were asked to depict a personal relationship. The included pairs run the gamut of familial to romantic, which all weave together to create a synchronized performance. You can see more films by Shaeffer on her website and Vimeo. (via Vimeo Staff Picks)
