Man-made Islands on Lake Titicaca
Handmade Islands of Tortura Reeds

Many years ago I read of a proposal to develop a huge island off the coast of Tokyo, but the idea of creating islands to live on is ancient. The Uros tribe of Peru say they existed before the sun, and they have been building their islands of tortura reeds since then. Tortura is like a large cattail. The Uros people also create boats from the reed. For more great pictures and information see http://gosouthamerica.about.com/od/topdestlaketiticaca/ss/FloatingIslands.htm.
