You see this a lot with movie directors or other photographers - they build a rectangle with their index fingers and thumbs to get a perspective on an upcoming shot. It's also a great way to make yourself look pretentious if you're pretending to set up a shot and you don't really know what you're doing.

With the availability of digital cameras inside smartphones and other small devices, it's unclear what the final benefit of this would be, unless they could figure out a way to put the camera in a small glove or something, then you could take photos without needing the camera or phone. Or better yet, have a camera directly embedded into your fingers like a cybernetic robot - but I guess if you're going to do that, might as well put the camera into your eye.
