Well thank-you. :-)

I've started playing with phong highlighting on the upper surface
coupled with noisy normals, though I don't really have anything to show yet.

It seems to me that phong or specular highlights are going to be much
more helpful than reflections.

You know you've been raytracing too long when you have archived more
than thousand rendered frames of an animation onto a CD to avoid ever
having to re-render.

Spherical and cylindrical patterns are equivalent when the camera is near the
ground. But if the camera is positionned high, only spherical is correct to
make things depend on distance.
