The Iraqi artist has a camera attached to three titanium plates, bolted into the back of his skull.

The camera is taking one photo every minute for the next year, and is feeding the images in real-time to a new show of contemporary art in Doha, Qatar. It also tracks his every move via GPS.

All this in the name of art. But the pain is getting to him just a little.

"I still have to treat it regularly with hot towels and salt water," he told BBC World Service.
