Fake - It's a Sculpture - This bit of public art blends nature with traffic in one confusing sculture. It’s Pierre Vivant’s Traffic Light Tree. A giant sculpture of fully-functioning traffic lights in London. For some reason it’s parked next to a roundabout near Canary Wharf. It was created by the Public Art Commissions Agency and it’s sure to confuse tourists, since roundabouts are confusing all by themselves.The light cycles of the Tree/Traffic Light mimic the action of Canary Wharf.
