The Secret Life of Machines is an educational television series presented by Tim Hunkin and Rex Garrod, in which the two explain the inner workings and history of common household and office machinery. According to Hunkin, the show's creator, the programme was developed from his comic strip The Rudiments of Wisdom, which he researched and drew for the Observer newspaper over a period of 14 years. Three separate groupings of the broadcast were produced and originally shown between 1988 and 1993 on Channel 4 in the United Kingdom, with the production subsequently broadcast on The Learning Channel and the Discovery Channel in the U.S. Contents Each of the Secret Lifes individual series covers a particular set of machines. The first addresses household appliances, while the second includes devices used outside the home, such as the car. The third series examines the contraptions and gadgets used in a modern office. Each episode was given an individual title, such as The Secret Life of the Vacuum Cleaner'''. Although ostensibly about a specific appliance or piece of technology, the scope of each episode was often widened to cover related technologies as well. For example, the video recorder episode looked at magnetic recording from its origins, and featured Hunkin and Garrod recording their voices on a crude home-made "audio tape" consisting of rust-coated sticky tape. Another aspect of the programmes was their use of humorous animations based on Hunkin's own drawings. These cartoons were often based around the historical figures involved in the development of a particular technology. Furthermore, the illustrations were an artistic commentary on modern society, including segments on lift fantasies (as shown in the episode "The Lift") and corporate disregard for individuals' rights (featured in many episodes, including "The Radio" and "The Car"). Each programme concluded with an epilogue consisting of an elaborate installation, which resembled an aspect of the machine or technology under discussion. One example was a giant statue resembling a robot, which had been built from scrap computer monitors, printers and other parts, which was blown up using pyrotechnics. Hunkin described the destruction as an allegorical point that computers are just a collection of transistors and lack "superhuman intelligence". Production All the series used a combination of mechanical models and animation to help explain various aspect of how the subject devices function. The animation for the series was done by Hunkin himself in a uniquely recognisable format. Episode
