So, what's the cross product of 1d vectors?
I think I'd be more worried if it parsed that and actually rendered a box on
the screen. Hmmm... if a ray were sent out that just happened to hit, say,
<-1,0,-1>, it would display it, wouldn't it? I'm not sure whether that's a
good thing or not--there's really nothing there for it to hit...

Truth is it produced nothing. It parses just fine but
nothing appears. I also tried using 2D vectors. This did
produce a result exactly as one would expect. It produced
a single face of the box.
How would Pov determine the inside of the object ? Would
it just take the normalized vector as it would a plane ?
