If anyone is talking about Mobius Strips then Cliff Stoll MUST be mentioned. This guys passion for Mobius Strips is infectious. [VIDEO] Also he was one of the first system admins to actually catch a hacker who was using his server in Germany in 1989. [LINK]

Yes, in the video I'm talking about [VIDEO] he says that a bootle has an edge (~3'40). A sphere does not have an "inner surface", it has just one surface. So does a potato. If you go from sphere to potato to bowl, when does an edge appear and does it have to appear, is my question.
