There are a couple of links to knots, at least one of which is dead, but I
can't see that one in the list. At least, it's not in the top level,
although it may be linked to from one of the existing links. I don't know
if I'm actually allowed to add links to the list, but I'll certainly
recommend this one: it's excellent, Janet! I could spend many hours
browsing that page.

I tried to do a simple trefoil knot many years ago in DKBtrace, using a REXX
program to calculate the positions of the spheres with trig functions. I got
some pretty images, but I was never able to get the exact shape I wanted.
