Perhaps I'm missing the point: besides a cool demonstration for what CSS can do (when aided by JS), why is this a useful idea?<p>For anything practical, would one not be better off not being a purist, and using images etc? After all, image formats were meant to store graphics. I'm sure I'm missing something, since I've lately seen a lot of these "pure CSS" things. But what is it?<p>[Edit: apparently, it is meant exclusively as a demo. And it's pretty slick at that]
