Williams, Kit -- Engines of Ingenuity
Art book by the guy who wrote Masquerade, the classic puzzle book.
Remember all that marquetry in the illustrations? He's really good.
This documents a working wood-and-metal model of an ancient gearwork
invention: a two-wheeled chariot which contains a compass that always
points north (as long as the wheels don't slip. Picture a
differential, but not exactly.) Gorgeous work.
