Worries that London 2012’s Cultural Olympiad had fallen at the first hurdle – as it seemed when the proposed Olympic Friend-ship, carrying a cargo of British artists and philosophers around the world, was scrapped – can be assuaged. The organisers of the London Olympics have, in fact, turned their course around: instead of this monumental, nationalistic, elitist, pretentious idea, they have moved to the local, the inclusive, the relatable.

A white kite flies high in black space, trembling, eagerly poised on a wind that shushes almost inaudibly. A man wearing black enters below, and in a low scoop of light prepares slowly in t'ai chi fashion with the calm of a ritual, making great black shadows with his arms and precisely angled legs. Then a small figure sheathed in black bodysuit, faceless, depersonalised, scuttles on and glues its feet to the man’s like a second black shadow. From then on every move the man makes is quadruplicated not only by his shadow but by his doppelgänger and its own shadow.
