This is a kind of science fiction too, but it really does exist. Science fiction doesn’t have to be fictional.

It’s Cedric Price’s aviary at London Zoo. It looks like it should unfold and walk about.

He made another, of the same type, for a rich guy who collected fancy birds that couldn’t be let out. But the land under aviaries needs time to recover, because the birds make a mess of it.

This other aviary would walk about the landscape, pushed by the birds landing on the side.

And this is one example of the second tradition of considering cities: picking an attribute that seems important, and working with that: “X cities.”

This particular one is a moving city.
