Reminds me a bit of the people that are into life-logging.
This has a completely different purpose though.
I actually considered life-logging at one point, but I'm still trying to figure out some technical hurdles, and a few other issues.
Mainly it's because I hate forgetting things, and take pictures obsessively anyway, so I figured why not?
But aside from technical challenges, I was also confronted with how to effectively disguise a set of cameras intended to show clearly what I'm looking at (which implies head-mounted), without looking like a complete and utter lunatic.
Copyright and privacy also comes into it, because while I wouldn't be inclined to make my lifelog publicly available, like some people do, there are those who don't like it if you take pictures of them.
Not to mention the headache of 'restricted' areas (london underground comes to mind), and those that cause issues with copyright (like a cinema, or museum).
Not to moments, like, say, having sex. (it's not such an issue if it's alone since I wouldn't intend to show it to people, but it could cause issues if there's another person involved.)
You might as why not just turn it off at moments like this, but the whole point of a life-log is that it records everything, so every time you turn it off, you're messing up it's purpose.
Of course, this 'art' project, while sharing some characteristics with a lifelog is definitely something odd. Who'd want to physically mount the camera to themselves, after all?
For that matter, it's on the back of his head, too...
Well, it takes all sorts I guess.
