Also note that the version of the pic that was posted as a link is an analglyph (spelling?) pic - i.e. if you wear red and blue glasses the pic will be stereo - or 3d! Cool! I also looked at POV-Ray some years ago and have again recently - it's yet another one of those things that will require more time than I have at the moment - but it's got a good user base and there's lot's apparently on the web about it. - Dave www.citizendave.com
