Generator of virtually infinite drawings based on epicyclic motions.

A polyline of three or more segments rotates around a predefined center, progressively changing its configuration. The center of rotation is located at the top outside the display area. The changes are made by rotating the first segment around the center and subsequent segments around the end vertex of the previous one. The segments from the second onward are drawn at each frame, and all traces are then moved down.

Depending on the lengths of the segments and the individual rotation speeds, the drawings can repeat in the same exact way after a few minutes or after very many years.
