Zajac didn’t make the film to demonstrate computer graphics, however. Instead, he was interested in real-time modeling of a certain theoretical construct. At the time, The Bell System was still deeply engaged in satellite research, having launched Telstar the previous year, with plans to continue developing communications satellites. Zajac’s model is of a box (“satellite”), with two gyroscopes within. In the film, he was trying to create a simulation of movement — the pitch, roll, and yaw within that system. He gives these particulars in an article in the Bell System Technical Journal, from 1964.
Zajac worked at Bell Labs from 1954 to 1983. He passed away in 2011; his last appointment was as part of the Economics faculty at the University of Arizona. For the latter part of his career, he specialized in the economics of communications and telecommunications.
