In 1990, a series of CGI animation collections began release on VHS tape. The Mind's Eye was the first experience many people (myself included) had with pure computer animation.
The best known segment from the first tape is Stanley & Stella in Breaking the Ice, which was first released in 1987. You can just watch it online now of course!
The animation style reminds me a lot of Reboot, a childhood favorite. It still amazes me how interesting this style is even today, really shows how much more artistry and vision matter than technology. I believe this is also the first public demonstration of a flocking algorithm.
