I'm going back through the @ataripodcast library and heard @savetz mention a fun interview with Mark Knutsen, who won first prize at a science fair with his simulation of the gravitational interactions between four stars, which he implemented in #ValFORTH on an #Atari800 after reading an article by A. K. Dewdney in the January 1986 #ScientificAmerican magazine, outlining how star cluster behaviour is investigated using computational models.
The interview with Mark Knutsen is on YouTube, where he demonstrates his program running in an emulator: https://www.youtube.com/watch?v=OwLgCPqi8FA
The same video on archive.org, if YouTube gives you the ick: https://archive.org/details/mark-knutsen

Thank you @savetz (and @floppydays!) for your time and effort arranging, recording, editing and publishing these interviews. It's important social history of a unique time and circumstance.
