I don't think that KnotPlot ever figures an explicit parametric
representation.  I think it works from points (the "beads") and splines.
That's a frustration for those of us more used to calculus and closed-form
solutions; but, I think, once one gets used to approximating from spline
points, the calculations can be much quicker and simpler (I'm still working
out a few of these, when I get the time, which is scarce right now....)
Also, I'd imagine that the parametric equations for some of the more
complicated knots would be hideous.
