I had a go at implementing this, but I have clearly screwed up the math 
somewhere, because the program is behaving very strangely.

(I've turned off all the fancy stuff until it's just a normal depth-1 
ray tracer, and the image still just consists of a few bent lines.)

So far I've found at least a dozen bugs in the ray/intersection code, a 
typo in the cross-product (typed an X instead of a Z), and I'm still 
finding more. What can I say? I fail at math! o_O
