I was listing some books on VCM, and ran across a mechanical EXCLUSIVE OR
demonstration photo using string. I had never seen or heard of such a thing
before and thought it was very cool! The book is Computer Hardware Theory, and a
jpg of the string XOR picture is at:

Excellent - thanks! My brain's having an off-day, but that design actually
"feels" a little over-complex - or were requirements placed on what mechanical
devices other than string could be used?
