Thanks for the very interesting submission! The followup post ("Gardens as Crypto-Water-Computers Redux") is also great! The photo of the Fontana di Diana Efesina (Tivoli, Italy) is amazing. Looks like something from Angkor Wat.

A couple of interesting examples in this (loose) subject area:

I like to bring this up whenever people start talking about not wanting GMO's.
If you are brushing your teeth with a toothpaste that contains peppermint oil you're ingesting a Atomically Modified Organism or HMO every day!
I prefer this article on the subject though.

Check out http://pruned.blogspot.com/2012/01/gardens-as-crypto-water-computers.h… to see a Soviet water-based computer. I don't know the details of it, but it appears to be able to solve PDE's by mapping the PDE you're solving to a hydraulic system. Since the flow of water is governed by PDEs, once you've mapped the problem to the computer you can just make some analog measurements of water flow to get the answer you're looking for. (Is this right?)
I have to wonder, thought, whether this is can really be called a computer. If you do, don't you also have to consider a simple integrator circuit one?
Error correction must also be somewhere between a total PITA and impossible, right?
