The artist cites arty-farty inspirations such as Magritte's painting of a pipe entitled "Ceci n'est pas une pipe", as well as "[questions of] technology and [...] of identity". Or maybe he's just a trouble-maker who deserves a day in a dark room with a police thug and a $5 wrench.
Of course any nerd would have spent months finding and writing drivers for managing a 1990s 480x320 pixel webcam and using that to produce the photo. It does rather beg questions of just how low a resolution a picture you can get away with though. And how would the police (etc) manage an HDR photograph (of one's reflection, out of focus, in a poor-quality mirror).
