Scientific American, I don't remember the issue.
It was an april fool's issue, I believe. If memory serves, the island
was called APRLFUL or something like that. The article showed how,
with clever arrangements pullies, toggles, springs and such, inverters
and simple logic gates could be produced. Entertaining enough.
The problem with that "computer" is that the logic gates have no gain.
