Blueprint has a dual Beijing/London Olympic special edition out. There's a look at the UK's olypmic village, which is currently behind a giant blue wall. There's a visitor centre which is, er, on top of an adjacent tower block. So the Blueprint editorial team commissioned an architect to design a blue-painted set of stairs to go against the wall - but the stairs were removed by security within 48 hours.

There was also an interesting interview with the only Chinese architect commissioned for Beijing. He said 'I'm glad no other Chinese architects were commissioned, because their work is not good.'

So - tact and diplomacy.

Beijing is going to disappear under smog, which is going to make it a firm favourite with the athletes.

I have no idea what London is going to turn into. It's supposed to be one of those urban regeneration projects, but apart from nice new stations, there doesn't seem to be a lot of that happening.

Maybe we could find some Chinese architects to make it more interesting?
