Some students joke that their teachers have eyes in the backs of their heads. A New York University professor is now closer to that reality, having had a camera surgically implanted into the back of his cranium. Wafaa Bilal, an Iraqi born photography professor at the university’s Tisch School of the Arts, had the procedure done at a piercing studio last month for an art project commissioned by a museum in Doha, Qatar, he said. “This will expose the unspoken conditions we face,” Bilal said Thursday. “A project like this is meant to establish a dialogue about surveillance.” The project is called “The 3rd I,” and will make use of the posterior camera by taking a snap-shot photographs each minute of Bilal’s everyday activities for one year, he said.
