WILLI WALTER, Swiss Pavilion, Expo 70, Osaka, 1970.
At night this giant, stylized tree lit up with a million bulbs turned into a kind of electric Mondrian (who probably influenced the design in any case). World Fairs have fed Technological Fantasy partly because they are in the business of selling it. The idea that Switzerland is an electric Christmas Tree is nice to contemplate.
