The phrase "L.A.-based artist" often describes someone who is a total dingus, but Stephen Glassman is a rare and welcome exception to that rule. He's developing a large-scale art project that turns billboards into hanging bamboo gardens. Each billboard's frame would be outfitted with planters, a watering system and environmental sensors, and Summit Media has already donated some structures. Glassman is trying to raise $100,000 via Kickstarter for everything else. Please, for the love of God, throw some money at this guy. After some of the billboards we've seen over the years, the only question is what took him so long to think of this.
