Last week I was particularly excited by the news that the British Pavilion was completed when David Miliband inserted the last acrylic hair into the “Dandelion”, as it has been nicknamed by Chinese people. Officially named “Seed Cathedral” it is a fuzzy cube formed from 60,000 slender transparent rods, extending from the structure. During the day, the 7.5-meter long rods will act like fibre optic filaments, drawing in daylight to illuminate the interior. At night, light sources at the interior end of each rod will allow the whole structure to glow.
