The Assumption of the Virgin (detail), 1530, by Antonio da Correggio
The Stalacpipe Organ is in the Luray Caves of Virginia. It plays by striking stalactites of varying sizes with rubber mallets and must be heard to be believed.

Ed Valigursky is one sci-fi artist to track down. Just look at that suave-bot-man. Although a volume of his work entitled Worlds At War has been promised, no signs of it have surface, yet. You can still find collectibles that his artwork has graced like the books of Isaac Asimov, Arthur C. Clarke, Ray Bradbury and magazines like Saga, True Adventures, Argosy, Amazing, IF and the list goes on.
