The BBC reports that Iraqi-born artist Wafaa Bilal's implanted headcam has been rejected by his body.
Bilal says he will continue to post images to his website from a camera placed around his neck.
Bilal, who fled Iraq in 1991, says the project is intended as a comment on today's surveillance society, where people in cities spend much of their lives under the watchful eyes of security cameras.
The aim of art is to represent not the outward appearance of things, but their inward significance. – Aristotle
