NYU professor Wafaa Bilal had a camera implanted in his skull last fall as part of a year-long art project, and now it is giving him a headache. The camera apparatus was installed by a body modification artist at a Los Angeles tatoo parlor. It consists of a titanium base fixed between Bilal's skin and skull. The camera is then attached with three posts. Bilal was undergoing antibiotic and steroid treatment, but his body still rejected the device and he was in constant pain. One of the posts has been removed, but the remaining two and the base are intact.
