Watch the video below and step back in time to the early days of CGI with ‘MAGI’, a company founded to model nuclear radiation transport.

Early (1970s through 1980) demo reel from MAGI/Synthavision, who would later go on to provide many of the CGI effects for the feature film Tron. Mostly television advertising and effects in the early years. Apologies for the lack of audio; YouTube flagged the soundtrack for copyright reasons.
