Hi--

Does any one know if anyone has ever tried to produce a theorem prover
for S-B's formalism?

Yes. William Bricken (now at the University of Washington doing VR)
produced a Lisp based LoF theorem prover a few year back with a nice visual
interface which animated the proof through a tree graph. I saw him
demonstrate it at the first Artificial Life workshop though his article
did not make it to the final volume. I have the paper which describes
the system.

Also was there ever any follow up to Varela and Kaufman's articiles on
Form Dynamics?

Not that I know, though there are further references to it in Kaufmann's
"Knots and Physics" second edition. Most are Kaufmann papers published
in obscure journals...
