National Geographic's The Incredible Human Machine [VHS]

Infused with a healthy awe of nature's handiwork, this film is a crash course in physiology. In just 60 minutes the video travels through every inch of the human body, highlighting the various engineering feats accomplished in the course of everyday activity. Tiny cameras expose the forest of taste buds on the tip of a tongue, the cavernous pores in a fingertip, and the eerie clenching action of vocal chords. While the live-action scenes are a bit dated, the visual effects created by x-rays, microscopes, and time-lapse photography are fascinating. --Claire Campbell
