Strudel is neat! A friend sent me a video recently of someone using it to make breakbeat music, which got me looking into it. I've known about live coding music for a long time but never actually investigated how it works.
I find the fluent API plus "display-oriented REPL" a very cool way to do things. The docs need a lot of work, though… The only API reference is in a sidebar of the REPL (i.e. not in the docs site), and discoverability depends entirely on guessing the name of the function. There's multiple ways to do things and all of them are explained with reference to each other, so it's very difficult to track down an authoritative, explicit overview of how something works.
