You may have seen some of the stories about the college professor at New York University that was doing an art project that had him mount a camera on the back of his head. The camera was going to shoot a photo every few minutes to post in a museum sponsoring the art.
The professor was Wafaa Bilal and he has announced that he had to have the camera on the back of his head removed because his body rejected it. One of the three titanium posts that was holding the camera on his head had to be removed via surgery last week.
The removal of the camera from his head has forced him to seek other means to take the photos. Might I suggest a backpack, or a necklace, or a Scarf, or just take the photos like a normal artist. "I'm determined to continue with it," Bilal told the Chronicle about "3rdi" which is described on his website as "a statement on surveillance, the mundane and the things we leave behind."
