Hi HN,I've an assignment to make a instruction video in my class. I'd like to try out creating the video with a programming language. I remember that one I saw a lisp based video creation/editing/animation software here on HN.My internet searches in the last hour only yielded  What I search is pretty similar. However it had a very beautiful UI and could be used/tested directly in the browser.I loved that software and I remember that the creator(s) also made a small game, a text editor for macOS and some other stuff. Each application was minimalistic and themeable with the same theme-specification, also created by them.Sadly I don't remember the name and can't find it in my notes or with my internet search engines.Does anyone know the one I seek or other video editing programming languages or DSLs?
