Description:
  • This meridian dial titled "The Point Where Things Change" was commissioned by the Redevelopment Authority of the City of Philadelphia. It is a large 8-foot diameter hoop aligned north-south. The gray painted hoop is supported at its base, covered by a narrow steel sheet cone also painted gray. The meridian dial and cone are slightly raised above a concrete pad. During the morning the shadow climbs up the AM side of the cone, at noon it rests directly on the point, and in the afternoon it starts to descend down the PM side of the cone. The Redevelopment Authority budgeted $18,000 for the meridian dial as a public art project.
