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 ..
