John's quest for the Trefoil knot

Well, so far I've managed to find a b/w stereoscope card with the
following:

Trefoil Knot

X = 2Cos[v]+5Cos[2v]
Y = 2Sin[v]-5Sin[2v]
Z = 7Cos[1.5v]Sin[-1.5v]

Tube segments = 180
Tube sides = 12
Tube diameter = 1

The stereo is quite nice and it can be viewed without causing brain
seizures. This was constructed by my friend Bill Kolb. I'll take a shot at
scanning it, but I have my doubts. If someone wants to try to put it on a
web site let me know and I can forward the file as a .gif or .jpg
attachment.

Somewhere I have a nicer version in color, but no idea where it is...
