There is an anonymous artist at work in Lyon, France. His special art involves filling potholes and cracked walls on city streets with beautiful mosaic designs, which he calls flacking. He started in 2016 after becoming hypnotized by the scarred surfaces of the old alley that housed his first workshop. My work is the story of the old city, where cobblestones have been displaced; a truck from the vegetable market tore off a piece of asphalt. Each becomes a flack.
