This is a few years old, but remains one of the coolest art projects I've seen on the internets. David Gallaugher of Dalhousie University created this mobile statement about the need to have more greenspace in urban areas. I wouldn't mind moving around Boston in one of those things. It would detract from the ugliness of Cleveland Circle while I was on my way to the Boston Commons and the public gardens. Shout out to Halifax, yall!
