Doing a project in which I make a model that consists of 3 rotating cylinders all which are wrapped in one of three pieces of a map. The toy is part of a museum exhibit and you are meant to rotate the three pieces until the map lines up properly. What is this called? The person who originally came up with the idea to do it saw it first at a historical museum in Italy somewhere. I know, super specific. Link to image. Help!
