The recent activity in these newsgroups with KnotPlot has kindled my 
curiousity. I've experimented a bit with the program and found the 
povray export function. What puzzles me is that when I render the 
knot.pov I get a knot that seems to be reversed. Looks like KnotPlot 
uses Moray coordinates. Is there an easy way to fix this?

  If you want to reverse the object itself, add a "scale <-1,1,1>"
to it. If you want the entire universe reversed, add a "right -x*4/3"
to the camera.
