Artist to Change Billboard Blight with Bamboo

Over the past few years, we've done a lot of stories about all those billboards that mar the L.A. skyline, but nothing like this. An artist by the name of Stephen Glassman has a plan to turn some of those signs into art with his project "Urban Air." And not just any kind of art, but natural, growing, sustainable art -- out of bamboo. He put his idea on Kickstarter and has already raised over $100,000.
