The "Triton City" – the work of the Triton Foundation whose principal members were Buckminster Fuller and Shoji Sadao – was commissioned by Charles Haar, a Harvard professor and the director of HUD, to design a floating city to provide housing in urban areas located near the ocean. A tetrahedron shaped module holding 5,000 inhabitants was designed and a comprehensive engineering report was submitted together with a large model which is on display in the lobby of the Lyndon B. Johnson Center in Austin, Texas.
