Street Cred

I live within walking distance of a local tourist magnet, Santa Monica's Third Street Promenade. At night the street fills up with street performers: jugglers, break dancers, balloon twisters, musical child prodigies, sidewalk preachers, and other temporary stars. Last night, among the acordionists and bucket drummers, I noticed the presence of those with digital projectors, who were using the hardware for persuasive purposes. For example, an animal rights group was showing a film that showed treatment of domestic pigs, and a creationist had a PowerPoint presentation cued up.
