Only at the first third and already delighted. He's moving between music, physics, programming in such a simple and pragmatic way, thanks for the bottom-up dynamic evaluation demonstration. Many many thanks.

links aside, he uses (and is a project contributor) http://overtone.github.com/

ps: they also provide a nice emacs setup https://github.com/overtone/emacs-live
