This Ferris Wheel can be driven by the AstroMedia Steam Engine (429.DMS) or the Stirling Engine (228.STM). It stands in the tradition of tin models meant to be driven by toy steam engines produced for the children of wealthy families at the end of the 19th century.

All our modern cameras have one common ancestor - The Camera Obscura: the light of the outside world falls through a pinhole onto the opposite wall of a room and produces an upside-down picture.
