I didn't know that about POV-ray. The only things I've rendered in it have
been floating in space, so I've never tried something hovering over a
reflective surface.
Is the POV file available for download somewhere? I need a 1024x768 version
for my Windows wallpaper :-)
Now, where can I get lotsa pink bricks...
