Harbor Fog, stilled buoys dream of a lost harbor, is a responsive sensor-activated interactive contemporary public sculptural environment located in Boston along the main pedestrian walkway of Wharf District Park Parcel 17, on the Rose Fitzgerald Kennedy Greenway. The first permanent public artwork along the Greenway, the concept was selected through a competition for commission by the Mass Highway Department, and integrated into site construction in collaboration with engineers during building of the Central Artery/Tunnel Project.
