Hello,

I came across the attached image the other day that I thought was beautiful so I
decided to look at raytracing again. I hadn't done any raytracing since about
1993 so the POVRAY program has changed quite a bit. I am using the 3.8 version
of POVRAY and it is amazing. I retraced one of my old images that took 33 hours
in the 1990's and today on my Mac it took about 10 minutes.

Anyway. I would like to understand how this image was produced because I would
like to do something like it for this years Christmas card.

It seems to be made up of Fibonacci spirals but I am not sure. I looked at the
POVRAY documentation for these types of spirals but I cannot seem to duplicate
the image accurately. I would guess that each color is its own Fibonacci spiral
but how they are positioned so they don't interfere with each other escapes me.

Any help or suggestions would be appreciated. If anyone has access to the actual
POV file for this image I would love to have it.

Thanks in advance.
