He is also a high school friend of SIGGRAPH Pioneers Chair Ed Kramer, and by chance sent him a link to this video while the submission process was active. This video is from YouTuber Scott Manley, he does a good job describing and showing some of the early CGI for JPL, highlighting Jim Blinn's work and talking about how it paved the way for the CGI in movies today.
