1. A three-dimensional topography representation generating hardware device, comprising: a frame; a plurality of movable pins within the frame; and a converting logic for converting a topographic map of a first region of a physical topography into a set of commands to individually control each of the plurality of movable pins, wherein each of the plurality of movable pins is selectively movable to create a three-dimensional representation of the first region of the physical topography based on the topographic map.
