It turns out that this is actually the first use of CGI in a film.





Yes, really.

Saul Bass insisted that the spirals, which represent 19th century equations, should be accurate and not drawn freehand, which requited both a pendulum and a rotating table (specifically an animation stand). Alas, no animation stand of that time could continuously rotate without its wiring getting messed up.

Hitchcock hired John Whitney who rigged up a WWII 850-lbs, 11,000-components anti-aircraft targeting computer called The M5 gun director to a platform. It was a mechanical computer which needed 5 soldiers to operate, but a computer nonetheless. He then placed cels on that platform and used a pendulum to achieve the needed endless rotation
