A truck driver, Joe Macken, spent 20 years creating a 1,350-square-foot scale model of New York City, including every building, stadium, street, and bridge. The model is now on display at the Museum of the City of New York. Macken's project began with a single building, 30 Rockefeller Plaza, and grew to encompass all five boroughs and parts of New Jersey and Long Island. The model features nearly a million structures and was made using balsa wood, acrylic paint, and other materials.
