Artist Francisco de Pajaro makes art out of garbage piles left on the street. He's built a huge following making little trash monsters in London this summer. According to de Pajaro's blog,Art is Trash, the artist first started painting on trash in Spain a few years ago.
"Rubbish is the only legal place you can make art on the street," he told James Buxton of Global Street Art.
