Follower Walk: Put Your Audience on a Seoul Street

Field notes

The simulator converts a user-entered count into a moving crowd arranged as a cluster, several rows, or a single line. Its scale model uses 1.2 meters between person centers, producing a stated 1,198.8-meter span for 1,000 people. The Seoul scene covers approximately 4.05 × 4.89 kilometers and is built from OpenStreetMap roads and building outlines, Mapzen terrain, and other listed elevation datasets. For very large inputs, the page says only the nearest 12,000 people are rendered individually.
