Life sentence prison M&M painter in trouble for his art business

The convicted murderer whose postcard-sized "M&M paintings" we've blogged here on BoingBoing is being disciplined by prison officials for running an unauthorized business out of his Pelican Bay cell. He made these paintings with ink leached from M&Ms and brushes bound from his own hair. He's in maximum security already, doing life. Now he's busted for… selling art. Link (Thanks, John)
