An innocuous water slide, for instance, suggests technologically induced pollution; happy tourists in yellow slickers walk through a tunnel to an observation deck, appearing unearthly and ominous, like aliens from a science-fiction film or mad medical technicians on their way to perform sadistic experiments; and the sterile hydroelectric installations recall both the dystopian nightmare city of Metropolis and the high-tech space station utopia of 2001: A Space Odyssey.
