Here's another entry in the "art or sport?" category.
Well, it's clearly art, but is that why it's interesting? I submit that it's interesting because all the work which goes into it and because of the fidelity to the photo. In other words, skill more than creativity. It seems to me you could get the same result with a mechanical device which made big prints of photos using ballpoint pins. (And there are actually printers which use pens.)
