Very nice indeed! I especially like the fact that the source is so well annotated, which makes me wonder: why bother with minifying it at all and not simply use the unminified source on Jsfiddle?
> Note that the goal here was to make the source code as
small as possible, not clarity; so even the original code
before minification is a horrible mess. This doesn’t do
justice to the elegance and simplicity of proper raytracer
code; I’m writing a book to right this wrong.
