Watch HDToday. A guided tour into the invisible world of cells, told through a collage of metaphors. Discusses and portrays the invisible world of cells, how they communicate with each other, work together, reproduce, and die, all to benefit the larger organism of which they are a part. State-of-the-art micro-cinematography is playfully intercut with parallel images from life at the human scale: a hundred lighted violins, imploding skyscrapers, pieces of film on the cutting room floor.
