“This is a digital dub of a 7 minute, 45 second 16 mm film produced in 1971 by the National Research Council of Canada, in Ottawa. It demonstrates not only one of the first ineractve computer systems for animation, one used for production, it was also an outstanding example of early user-centred design.
The system was developed by Marceli Wein and Nestor Burtnyk, both of whom won Academy Awards for this influential work. For some additional information, see also:
