For the daily prompt thing I'm doing, I ended up going down a rabbit hole about windmill sails and came across this story of a miller who restored the last of what used to be many windmills--"the highest concentration of windmills in the Iberian peninsula"--on a mountain in Portugal. Here he is with his windmill in 2019:

He's using the mill to grind ancient wheat grains; he says ants prefer wheat grains that don't have pesticides.

Oh, and those clay pots hanging on the arms of the windmill? They are each tuned to a note in the key of C Major, and you can hear what they sound like in this soundcloud file.
