“This month, a New York-based Web site that celebrates graffiti and other street art began testing a system” that would allow “art lovers to download images created by emerging artists onto the video screens of their cellphones. Calling it a “curated online art gallery for your mobile phone,” the founders of the Web site, woostercollective.com, are hoping it will provide a new way for struggling young artists to make money, in much the same way that a songwriter can earn money from radio play or an actor from reruns.”
