In a street in Saint-Etienne, France, a branch of a particular purple flowering bush has suddenly become famous. Why? Because street artist OakOak has incorporated it into his latest work, a portrait of Sideshow Bob, the evil serial killer from TV show 'The Simpsons'. The branch with purple flowers has become Sideshow Bob's trademark mop of hair. OakOak, a Saint-Etienne local, is known for incorporating elements of the environment into his art to complete it. Check out some of his other works, here.
