As one who took part as a model for one of Spencer Tunick's mass nude gatherings (Cleveland 2004), I appreciate the photos available on the Internet of Mr. Tunick's "installations,"as he calls them. The one that intrigued me the most was the portfolio shot for Greenpeace International featuring hundreds of naked participants artistically arranged on the largest glacier in Switzerland. The URL is enormous, but thanks to TinyURL it's now manageable: Nine large photos are available in the directory.
