Temmel stamped angels' wings on the backs of 71 participants - Japanese, 
English, Swiss, Icelanders, Puertoricans... who did not know each other. A 
person's back is a part of the body that is never directly visible to the 
person himself. With the knowledge of being a part of an art project, these 
marked persons evolved, as the project progressed, into a globally linked 
human network, a human sculpture.
