He is an artist best known for wrapping the Reichstag in Berlin and for siting thousands of colored umbrellas across valleys in Japan and America. Now Christo is creating for Abu Dhabi a colossal structure that he claims will be the world's biggest permanent sculpture, made out of 410,000 multicoloured oil barrels.
