Livecoding Music and Graphics in the browser

Livecoding, or the act of coding in front of an audience, possibly with your code exposed on a big screen, is kind of a niche art form, with environments like SuperCollider and Impromptu being the most popular choices. I went out to try to build a minimal, capable and usable environment that would run in a modern web browser. I will talk about (and demo) the system itself, but also will speak about the challenges and the details of my solution.
