Diary: Pick of the week - M&C Saatchi/Transport for London

Kunal Dutta is ready to part with his car keys after watching Transport for London's "signs" spot from M&C Saatchi:

"I've never been much of a cyclist, but this ad makes a compelling case for trying again. Why? It's a simple idea, beautifully executed. Take existing pieces of cycling signage. Bring them to life with stunning grading, a transient soundtrack and shots of the city that would have Richard Curtis smiling. Then let the jury decide how to get around London this summer." It was written by Tom Drew and Uche Ezugwu and directed by Emil Moller at Sonny.
