Thanks to the folks at Los Angeles Transit, I now know what to do with all these leftover political billboards.

Imagine sitting in traffic during your daily commute and instead of seeing the clutter of countless billboard advertisements you see gardens floating in the sky. That’s the kind of green experience Los Angeles-based artist Stephen Glassman wants us to have as we travel through our urban landscape. His Urban Air project hopes to transform the steel and wood frames that hold billboard advertising into suspended bamboo gardens.

Glassman’s been creating large-scale bamboo installations across Los Angeles since the aftermath of the 1992 Los Angeles Riots. He came up with Urban Air because—like many of us who live in congested cities—he saw a need for more fresh, green space, and a greater connection to humanity. The idea won the 2011 London International Creativity Award and proved so inspiring that Summit Media, a billboard company based in Los Angeles actually offered to donate billboards along major streets and freeways.

You can learn more about the project here. What a great ad this would make for a local landscaper, nursery or garden center. Vote landscaping in 2012!
