I took part in an interesting event on Saturday, the ‘Great Trafalgar Square Freeze’. The basic idea is you get loads of people to gather in one place (I heard about it through the magic of facebook), a trumpet then sounds and everyone freezes into a position leaving others wondering what’s going on.

Anyway it was quite a spectacle, and really interesting to gauge people’s reactions - someone has put together a video of the event here, also check out the New York video which for some reason seemed more effective …
