The Richard Rogers exhibition at the Design Museum is very good. You should go. It's full of those lovely models that architects make.
Those models must make for brilliant "pitch theatre".
But it's also got great typography. Those great big signs are gorgeous. Really lovely.
But you should go because, in a bit of a shock for the Design Museum, the other exhibitions are worth seeing too. There's some very cool, interesting and playful stuff from Industrial Facility and there are some colourful photographs from Tim Walker. And of course they let you take lots of pictures.
