I saw on the Flickr blog
a post about the Fourth Plinth
in Trafalgar Square. The plinth is usualy reserved for statues, but is currently empty. So there is a project where, for one hour, 24 hours a day, for the next 100 days, a person will be standing in place of the statue. Sort of live art. There's a live webstream
so you can see what's going on at any time. Apparently they had 22,419 applicants for the 2400 available spots. Poor guy right now is standing in the rain, but his hour is just about up...
