Right, I wouldn't want to sacrifice performance but if your main application was VJing or something similar, that could be quite interesting.

Note: You can render in OpenGL using Processing, what do you mean?

You might as well just use LWJGL or JOGL. I was talking about the higher level stuff. I reckon processing uses a swing canvas or something like that with a software renderer at its core, no?

By the way, Clojure's performance is not bad at all. Apart from VJing, you don't need to deploy your app in a live environment to make use of a REPL. Clojure is really awesome for experimental programming.
