I used to love those biology books where the digestive, reproductive, and respiratory systems were all on different transparent sheets and you could superimpose each one and see how they all fitted together.

I think town planners, architects and sculptors who repurpose industrial equipment and warehouses and silos — and even whole transport networks — must have been fans of these books too.
