Peep this amazing animation, The Seed, by Johnny Kelly, which follows the interesting path of one small apple seed, including a quick trip through the human digestive system including the maze-like wonders of the intestine. The stop-motion human body made of paper is quite a sight to see -- the faceted organs beat as the seed travels through the esophagus and withstands the acidic rigors of the stomach. See the incredible amount of labor that goes into stop-motion animation by watching The Making of The Seed. Fantastic!
