What a fantastic "signature project" for London - we'll showcase something they had in Berlin, in only slightly different form, about a decade ago. I know there's nothing new under the sun, but is this really the best we can come up with?

Bravo for the Cultural Olympiad. Sometimes the arts in this country feel as if we were on an island in the middle of nowhere. Oh hang on a minute...
