UK pavilion at Expo 2010

The UK pavilion at Expo 2010, colloquially known as the Seed Cathedral, was a sculpture structure built for the 2010 World Expo in Shanghai by a nine-member conglomerate of British business and government resources directed by designer Thomas Heatherwick. Referencing the race to save plant seeds from round the world in banks, it housed 250,000 seeds at the ends of 60,000 acrylic fibre-optic filaments which projected both outside and inside the building.
