Nagle asked me to make a video of Flowsheets so he could show it to John Maloney, so I threw this thing together:
In the video, I sort of lazily show some of the prototype I've made so far, and show how you would make a real program. I don't do much to explain the idea or why I think it's important, so this video is a lot different than a real public talk I'd do. I'd explain more context and also show more exciting examples.
Anyway, enjoy!
