Here are some examples of Spencer Tunicks work. He arranges mass nudathons and photographs, huge events in which hundreds of people pose. Some are sheer genius, like the one below in Bruges or the one in Central Station New York. They just work. They're not titillating or cheap. Just large and grand. The two below are of places I've been too; San Sebastian beach and Amsterdam (though getting people in naked in Amsterdam is hardly a stretch).
