A London's first La Petit Nuit Blanche on Saturday, they had something I would have spent all night at if I didn't end up getting a shitty headache. It was called photocircus. Three photographers set up an overhead projector lighting a brick wall in a parking lot. They had boxes of assorted costume pieces and props. You could dress up and get your picture taken doing whatever. On the brick wall beside they were projecting the images from the night in a huge slideshow.
This is one of my favourites that's been posted, but I really hope they put up the one of the guy who took of his shirt, held a square of plexiglass with holes in it directly in front of him and swung a piece of dryer tubing around on the other arm, and had a pot in his mouth.
