The Bicycle Company (1984)

Nostalgia! Past visitors to Los Angeles' Museum of Science and Industry might recall this animation from a Hewlett Packard exhibit dating from 1984. The looping animation was coordinated between two projection screens. Sadly, the exhibit (and many others) are now gone, the museum replaced by the California Science Center, a much larger and more modern building that's mostly empty, with only a scant few inferior and usually broken-down exhibits.
