If you’re in London and haven’t been down to the Global Cities exhibition at the Tate Modern, you’ve got five days to do so! Paul and I were down there last week and it’s good. 2007 is the first year that the earth’s population has balanced 50/50 between rural and urban, and the exhibition explores some of the world’s great cities under the headings of size, speed, form, density and diversity.
There’s some arty stuff, like the odd but appealing video installation of a guy rattling a stick along fences in London, making all kinds of rhythms. There’s some great photography, and plenty of educational facts. The stuff about population density is particularly eye-opening – I think London is overcrowded, but we have 4,500 people per square kilometre. Cairo has 36,500 people per square kilometre.

That is mind boggling density!
