Went to Strange Clay at the Hayward Gallery. I feared this might be a bit austerely intellectual, but in fact most exhibits are attractive as well as interesting, and several are humorous to varying degrees. There is a self-portrait with critique by (Sir) Grayson Perry and a piece by Edmund de Waal, better known to me as the author of The Hare with Amber Eyes. I’m afraid the latter is the least enjoyable thing in the show: small white pots in vitrines hoisted above your head. Katharine rightly said it looked like additional light fittings… Generally though, the show is a lot of fun.
