An artist, UC Santa Cruz professor of art history Mary Holmes would say, is someone who makes the invisible visible. Does that make the Internet an artist? These examples of the invisible made visible impress me:
1. Security footage of a man stealing two chairs. (Thanks to HuntGrunt.)
2. Tracking data at the Shangri-La Diet forums reveal what weight loss is like for other people.
I think the other extreme — the very visible made extremely visible — is also art. Here is an example: David Caruso one-liners. Too funny not to be art.
You might enjoy reading about an interactive art/internet experiment done by Japanese artist, Katsuhiko Hibino, where particpants were invited to step beyond themselves. And the work of artist, Noriyuki Tanaka (who joined Hibino in that experiment). Also, you may enjoy the RENGA interactive art project conceived of by artists Toshihiro Anzai and Rieko Nakamura.
