Veteran graffiti artist Saber took his protests to the sky yesterday, scrawling his grievances about the current mural moratorium on the great big blue canvas above LA. His message made the news and lit up the twittersphere. He explains exactly why he hired five private jets to tag the sky for him on his blog. Kind of brilliant! Where we were in Silver Lake, we managed to catch a glimpse of his fleeting “rebel artwork.” Did you see it?
