You can specify two different colors for the angle-dependant reflection, 
but that will only give you two colors and will only affect reflection. 
What's needed is an angle-dependant pattern, like slope but relative to 
the incoming ray. I think someone once implemented this...

Another possibility, which would also be much more flexible, would be to 
make the intersection and ray information available to functions...you 
could then implement your own custom angle-dependant pattern.
