Hi,

even if you don't understand german, have a look at
http://phong.informatik.uni-leipzig.de/~kuska/visualsupp/visualsc.pdf

pages  31--55. All pictures are made with Mathematica and some small
additional tools. I can tell you it *is* so easy as it said -- no
picture
took me more than a 1/4 hour ..

Regards
  Jens
