After visiting the 2010 Shanghai World Expo last week, I decided that the night time is definitely the right time to visit. During the day the crowds were overbearing and most of the pavilions less than enchanting. However, when the sun goes down, the expo turns into a festival of lights. Some of the clear architectural winners in my book were the Spanish, Korean, Nepalese and Danish with the UK Pavilion taking the gold. Designed by Thomas Heatherwick, the six-story structure is stuck like a pincushion with 60,000 willowy rods that glow and quaver in the breeze. The rods extend from the interior where at the root of each a plant seed is seamlessly inserted. The UK Pavilion is supposed to reflect the British love for gardens and emphasize the need for green space in cities. You can read more about the concept on the UK Pavilion homepage.
