This really needs an accompanying introduction. Why this? How'd you get this idea? What's easy to do using this technique that's not easy in traditional programs? It's too far out for me (and I guess for others as well) to just "get" instantly.. I'm not sure I want to spend a few hours playing with this just to find out it's not too interesting, then again, I might do that anyway.
