Mobile Parks

Four architecture students from Halifax, Nova Scotia, spent the day yesterday walking around town in a grassy wheel to make a statement about the lack of green space in the city. Their clever approach was reminiscent of a project carried out in Sierra's neck of the woods late last year, when the San Francisco-based art collective Rebar turned a downtown parking space into a temporary park. What do you think about art as activism? Can it make a difference?
