ADDENDUM: Apparently this is hoax. According to Wired, Skullphone paid Clear Channel to put up his work rather than hacking their network. So much for street cred pal, I think it’s fair to says your days as a street artist are done.

Graffiti is apparently going high tech these days. Street artist Skullphone found a way to hack several Clear Channel Billboards in Los Angeles and insert his own art into them. While this won’t last as long as spray paint, you could potentially tag every electronic billboard in America at once. How’s that for street cred?

Thanks to the punx over at Swindle for the tip
