Grayson Perry's Tomb of the Unknown Craftsman at the British Museum has been on my to do list since it opened in October. I defy anyone to see his works there and not marvel at the skill and ingenuity of this incomparable artist. As I exited through the gift shop (with a nod to Banksy) I was presented with this view and felt like I'd been transported to the passage that leads to the Treasury at Petra. The exhibition has been extended to 26 February. Just go!
