You might want to check out the custom DSLs made by livecoders. There's an old Wired article about them (http://www.wired.com/science/discoveries/news/2006/07/71248 http://www.wired.com/science/discoveries/news/2006/07/71248), and this is a livecoding wiki: http://toplap.org/index.php/Main_Page http://toplap.org/index.php/Main_Page . I can't find it now, but I recall seeing a really in-depth Lisp language for livecoding. There are screencasts you can check out.
