There's a book called "Possible Palladian Villas" which gets into procedurally generated houses (in the style of Palladio), and that kind of thing came up—they'd run their algorithm to generate some houses, and then notice details in what was generated that were just... off. Not impossible, just... not quite right, either. Things you wouldn't think about unless you saw plans for a house that didn't consider it. So they'd tweak their algorithm, and re-run it, finding new details to fix. It's a cool book.
