notes:

Good job.  Some errors make the output look
bad, but turned out to be fairly minor.

You have a bug in your ray casting func that 
leads to wrong radiance being gathered.

You forget to multiply reflective radiance
with the shininess of the object before
passing it on.

You use SurfnOS directly in your plane
in your plane intersecting routine.  This
is fine when you find an intersection, but
means you reset this value even when no
intersection found.
