Eartha is a 3-dimensional scale model of our earth with mountains and landforms in full 3D, that rotates and revolves, simulating the earth’s real movements. Eartha was given the title of "World's Largest Revolving/Rotating Globe" by the editors of the Guinness Book of World Records in 1999, and still holds that record today. It measures 41.5 ft in diameter. Unveiled July 23, 1998 Eartha took two years to build and represents earth as it is seen from space. It rotates and revolves on a specially designed and built mechanized, cantilever arm. http://www.delorme.com/about/eartha.aspx
