Between 2011 and 2016, Cally Trench, Annie Rapstoff and Philip Lee collaborated on projects that celebrate zebra crossings. Unlike traffic-light operated pedestrian crossings, zebra crossings require a human interaction. The driver must notice the pedestrians and stop to allow them to cross, and they in turn usually acknowledge the driver with a wave or nod of thanks. As drivers we often feel separated and insulated from the outside world. Zebra crossings remind us - whether driver or pedestrian - of the humanity of the other.
