Back from the Nuit Blanche, an all night arts festival in Toronto. Perhaps the oddest thing I saw were people cavorting over and around litter bins, and pole dancing with a lamp-post.
More sane, if that's the right word, were the Toronto Arial Dance troupe. It was modern dance whilst dangling from a trapeze. They have a website:

Performance art, like installation art, tends to fly past me I'm afraid.
