The other thing that has stuck with me is Kirsten Lavers' Admitting the Possibilities of Error. It was the kind of simple and immediately graspable concept that works so well in the arcade- the artist drew a huge circle and then tried to replicate it in concentric inner circles, by hand, one by one. This led of course to error and slow correction. It played to another strength of the arcade by providing an opening for conversation and contemplation with the artist while she worked, in a direct and genuine way, without obligation. Each circle was made with a different pen provided by the public, and their names added around the edge. We were encouraged to think about mistakes, and especially the ones we don't regret. The finished piece is being silently auctioned for the arcade here.
There was also a stormtrooper who gave counselling, which sounds like it was great and I'm sad I missed it. Great music too, and lots of stuff I didn't have time to investigate properly. I like the way the arcade makes artists come to the public rather than making them go to the artists. Like Sam said in his opening speech, it's a gift, made better by the fact we can take it or leave it as we please.
