The Watercube (swimming arena) for the Beijing Olympics was designed by PTW architects (& Arup Engineers) from Australia who won the design competition by popular vote. The square cubic shape represents the Chinese symbol for earth, while the circular shape of the Bird’s Nest Stadium in the background represents Heaven. The design on the outer skin of the Watercube was inspired by the random shape of soap bubbles.
MB took this shot approx 4 years back on a visit to Beijing, from the high floor level bar of a nearby hotel. Quality of the pic not great due to the bar window reflections.
