The Secret Life of Machines

Tim Hunkin explains how the machines we use every day actually work, using a fascinating combination of experiments, analogies, animation, and larger-than-lifesize working models. The TV series was the outgrowth of a series of cartoons for the Observer newspaper called "The Rudiments of Wisdom", which Tim researched and drew for 14 years. The theme music is a version of Dave Brubeck's "Take Five" by Val Bennett, retitled "The Russians are Coming".
