Sidewalk (or pavement) is a 14-cell still life made up of two islands that are by themselves referred to as sides. An individual side can occasionally be useful as an induction coil.
Peter Raynham found a 4-glider synthesis for the still life in 1973, which is based on a head-to-head collision between two pi-heptominoes.[1]
