The Roanoke Valley Reef is a satellite reef of the Hyperbolic Crochet Coral Reef, a project of the Institute For Figuring created by sisters Margaret and Christine Wertheim. Margaret Wertheim talks about the project in the TED video linked to from here titled "The Beautiful Math of Coral." This is an excellent introduction to the project.
