Last May, we had the privilege of visiting Expo 2010 in Shanghai, where we got first looks at the inventive pavilions. Where else, other than at an international exposition, can you tour a spiny Seed Cathedral or make contact with a giant robotic baby?
Since their inception, World's Fairs have whisked millions of visitors to far-off places: Lisbon, Osaka, New York, and, of course, the future. The tradition of World's Fairs goes back to 1851, when London hosted the Great Exhibition in Hyde Park's Crystal Palace. Between then and Expo 2010, World's Fairs have evolved from industrial exhibitions to platforms for cross-cultural dialogue, to vehicles for promoting the host countries themselves.
