You’ve got to think of him as a communicator, with an interesting medium whether or not you agree with his message. Kinberg’s tactic, using a bicycle equipped with a laptop and a wireless connection, just got him arrested. His techno-artistic project involves spraying the sidewalk with messages –protest messages at that– uploaded by visitors to his Web site.

His arrest on Sunday, opens up an interesting debate on what constiitutes a legitimate guerilla campaign. Recall when Micsosoft plastered sidewalks with plastic decals of the MSN butterfly in 2002? New York city fined then $50, but no one at the ad agency (McCann-Erickson) got arrested for that. Also, Kinberg was arrested while talking to MSBC’s Ron Reagan (see Chris Mathew’s blog) and not while riding his bike!

This trend bears watching, because PR and MarCom is poised to start appropriating creative tactics that tap into technology like this.
