Going into Orbit

Anish Kapoor's Orbit, viewed from platform 10 of Stratford Station. The train driver who told me off for taking this photo ("It's against the law to take a photograph on the railway, did you know?" he said. I said I didn't and explained about Bilpfoto - it didn't help. Does anyone know if this is correct?), he said that it is just four men doing the work to put it all together. Big as it is, you can't see it from many parts of Stratrford station on account of the new Westfield Centre getting in the way.
