the "Cornell Box"??

Are my changes really that extesive, relatively speaking?  I haven't
looked at the source to the dispersion patch but I'd guess there's some
kind of loop that traces rays of different wavelengths...  and those
rays still obey the same rules.

Speaking of WyzPOV, I have a new version to send you which fixes some
major bugs.

Speaking again of WyzPOV the link on your home page is not responding -

No, probably not.  It's just that the code got shuffled around a lot
when I tried to make your stuff work with 3.1a, so any other changes
to the same area would lead to lots of merge conflicts.  In any case,
it looks like Nathan got it to work in MegaPOV, so it must not have
been as hard as I was telling myself it would be.

I know...  the guy hosting it is having some problems with the phone
company.  He told me it should be back up fairly soon.
