knots in latex

I found a site full of examples to create knots in latex and it's quite a pain to paint them. They look nice, though. You basically paint them via xy and then place *"holes"* in the parts where you want to make a crossing. Here is an example:
 "LEFTTOP";"RIGHTBOTTOM" **\dir{-}; \POS?(.5)*{\hole}="HOLE";
 "RIGHTTOP";"HOLE" **\dir{-};
 "HOLE";"LEFTBOTTOM" **\dir{-};
