CHINA/Beijing/National Aquatic Center/17June2008:A soldier stands guard outside the National Aquatic Center at night. Designed by Australia's PTW Architects, its facade appearing as a cube of soap bubbles, it seats 17,000 people. The exterior is made from a high-tech lightweight translucent plastic that is also very energy efficient in saving an estimated 30% in power consumption by comparison to a traditional design. It houses 5 pools - one able to create it's own waves. It's outer surface looks like soap bubbles. It will host all swimming and diving events at the 2008 Olympics.
