The creator, Armando
http://armandomoncada.com/home.html was there, and explained it was a type of plantscape. The owners were concerned they would get all the glare from the oncoming headlights of cars coming down the street that runs directly toward their house. The purple tubes are for irrigation. People driving by are supposed to see the wooden side, and the people living there will have a verticle lawn.
Ok, everyone, I told Armando I had published his work to YouTube, and talked about it here, so he'll be along at some point to look at our goofy and serious guesses. He thought it was funny I bothered to do all that.
So let's all send our greetings to Armando!
