A lot of the responders are missing something - this is just a demo of a "zooming interface". It's included as an aside, not intended to be part of RCHI. RCHI itself is more akin to a text editor (though it's the best-designed one I've ever heard of). I'd recommend picking up Raskin's book, The Humane Interface, for a full understanding.
