A girl named Elastika: an animated adventure in office supplies
Animated by Guillaume Blanchet, this new stop-motion short called A Girl Named Elastica tells the brief story of a girl who leaves her home to adventures around the world. Probably the most notable aspect is the ingenious use of thumbtacks and rubber bands to create the majority of the animation which takes place entirely on a small bulletin board.

I love the holey tracks the pins leave behind on the paper, footprints in the sand, form following function and so on. Interesting play on scale too.
