It's indeed probable.
When I rendered it the first time around, it was a heinously grotesque form.
Then when I saw that Phi equals approx 1.618, I thought that maybe that was the
problem and vnormalize( )ed all the vertices and it just _looked_ like it was
ok.
Such are the dangers of "massaging the data".

The interesting thing is how well the macro outputs looked - it wasn't obvious
that the basis array of points was wrong.

Thanks for looking that over and spotting the errors.

I'm actually surprised that such a thing hasn't come to anyone's attention until
now.

While you work on that, I'll start working on breaking something else.   :D
