On September 13, 1983, Jim Henson and The Hitchhiker's Guide to the Galaxy author Douglas Adams had dinner for the first time. Henson, who was born on this day in 1936, noted the event in his "Red Book" journal, in characteristic short-form style: "Dinner with Douglas Adams – 1st met." Over the next few years the men discussed how they might work together—they shared interests in technology, entertainment, and education, and ended up collaborating on several projects (including a Labyrinth video game). They also came up with the idea for a "Muppet Institute of Technology" project, a computer literacy TV special that was never produced. Henson historians described the project as follows:
Adams had been working with the Henson team that year on the Muppet Institute of Technology project. Collaborating with Digital Productions (the computer animation people), Chris Cerf, Jon Stone, Joe Bailey, Mark Salzman and Douglas Adams, Jim’s goal was to raise awareness about the potential for personal computer use and dispel fears about their complexity. In a one-hour television special, the familiar Muppets would (according to the pitch material), “spark the public’s interest in computing,” in an entertaining fashion, highlighting all sorts of hardware and software being used in special effects, digital animation, and robotics. Viewers would get a tour of the fictional institute – a series of computer-generated rooms manipulated by the dean, Dr. Bunsen Honeydew, and stumble on various characters taking advantage of computers’ capabilities. Fozzie, for example, would be hard at work in the “Department of Artificial Stupidity,” proving that computers are only as funny as the bears that program them. Hinting at what would come in The Jim Henson Hour, viewers, “…might even see Jim Henson himself using an input device called a ‘Waldo’ to manipulate a digitally-controlled puppet.”
While the show was never produced, the development process gave Jim and Douglas Adams a chance to get to know each other and explore a shared passion. It seems fitting that when production started on the 2005 film of Adams’s classic Hitchhiker’s Guide, Jim Henson’s Creature Shop would create animatronic creatures like the slovenly Vogons, the Babel Fish, and Marvin the robot, perhaps a relative of the robot designed by Michael Frith for the MIT project.
