I visited a scientist who had a helmet with magnetic fields controlled by computer sequences that could profoundly affect your mood and your perceptions.

IBM was the original contractor for much of the computer interface design on the film.

Clearly, if we'd had the kind of computer graphics capability then that we have now, the Star Gate sequence would be much more complex than flat planes of light and color.

But as far as the concept of HAL, who HAL was, his character - I had no role in creating him.

There were IBM logos designed for the film, and there were IBM design consultants working with Kubrick on the layout of the controls and computer screens.

My particular aesthetic of light and color and design wouldn't change as a result of working with computer graphics rather than with slit scan or miniatures.
