An interactive piece that redraws any closed shape — a freehand drawing, an uploaded image, or the outline of a country or city — with a chain of spinning circles. You can change the number of circles to see how the approximation improves, and display the spectrum of circle sizes and the breakdown into sine waves in x and y. Circles riding on circles is the same idea that drives spirograph curves.
