Weekly Photo Challenge: Geometry (4)

The Water Cube (Beijing National Aquatics Center) is located in the Olympic Green, the focal point for the Beijing Games.  The cuboid shape of the Water Cube is a reflection of the Chinese symbol for Earth, while the adjacent elliptic form of the Birds Nest (see Photo Challenge (3)), represents Heaven.
The outer wall of the Water Cube was inspired by the natural formation of soap bubbles ( using the light, translucent but strong ETFE as the facade material). It is based on the Weaire-Phelan structure, a structure devised from the natural pattern of bubbles in soap lather. It was realised that a structure based on this unique geometry would be highly repetitive and buildable while appearing organic and random. The result is a very simple regular building form, with very complex geometry in the façade which offers stunning aesthetics effect.. . . . . . . . . . . . . . . . . . .
