Wow, I wasn't even aware there was an opening to the Voyager 2 Saturn animation (which I had of course seen). I'm seeing Blinn's Mimas animation for the first time now. Yes, it's remarkable what he was able to do on the extremely primitive (by today's standards) computers back then.

Actually Blinn's animations were a major early inspiration for me but it never occurred to me back in the 1980s that one day I'd be able to do something vastly superior (I was experimenting with primitive wireframe 3D graphics back in the mid/late 1980s). The wonders of today's software and hardware...
