Ringworld

Larry Niven's sci-fi franchise of Ringworld and Known Space stimulated my teenage years. Ringworld was a gigantic structure, a ribbon habitat that encircled a sun. I imagined, as I bicycled around my home of Lulu Island, that the terrain was part of Ringworld. Niven reinforced my belief that some aliens did not have humanoid shape.

Larry Niven explores the theme of teleportation and its impact on society in the Ringworld sci-fi franchise and the newer book Red Tide.
