A few years ago I started reimplementing this very cool early 80s animation by Larry Cuba:

The sources are available here:

The goal here is to understand what are the underlying algorithms on all of these scenes. I was able to figure out a few of them, but left many other scenes still unimplemented. I hope someday I can have a complete implementation and I welcome anyone else interested to submit pull requests. (Please, let’s keep it dedicated to the public domain, since I do not own the rights to the original work).
It would also be amazing if someday we could see the source code for the original implementation.
The original animation was implemented using the ZGRASS programming language on a Datamax UV1 computer. As I am also a computer history enthusiast regularly contributing to the MAME Project, I would love to attempt emulating the original system and rebuild/rerun the animation.
I have no idea if the original sources were preserved, or how one could get access to it nowadays… But it would be truly amazing to see it
