Inhabitat recently posted a story about a new photosensitive material that bends in sunlight. An alternative film, called c))motion, is already in production but has a slightly different application. In short, the film is a plastic laminate that acts like a bimetallic strip, bending when heated or placed in the sun. The innovative film is inexpensive, similar to the material used in potato chip bags, and can be used to passively ventilate attics or operate a window shade inside a double pane window.
