I was thinking of various examples in 'Godel, Escher, Bach', and it's
years since I read it. Here's a URL I just Googled that may be
relevant:

http://www.geocities.com/ResearchTriangle/6100/geb.html

>From memory, Hofstadter decribes 'implementations' of computations that
involve the detailed behaviour of anthills, and worse yet, detailed
descriptions of 'Einstein's Brain' listed in a book that you can
supposedly ask questions and receive answers! Trouble is, Hofstadter is
such a brilliantly witty and creative writer that I could never be
completely sure whether he was deliberately torturing your credulity by
putting these forward as tongue-in-cheek reductios (like Schroedinger
with his cat apparently) or whether he was actually serious. I'll have
to re-read the book.
