Hi Jeff, Yes, Jeff, there is! Check out http://sciencenorth.on.ca/AboutSN/polaris/index.html for a partial globe called Terra whose size is 1 millionth that of Earth. ( One mm on Terra equals 1 km on the surface of Earth.) The morning and evening terminators show very well on the exposed portion of Terra. A hundred yards due south is Celeste whose dimensions mimic Terra's and whose gnomon's shadow tells dialtime conventionally.
By the way, the radii of both Celeste and Terra is 20/pi meters. Do you know why? A nice tidbit here!
