Fourier Epicycles

This animation decomposes complex paths into a series of orbiting circles using the Discrete Fourier Transform.

Remarks

Draws a shape using rotating circles (epicycles) derived from the Discrete Fourier Transform. Each circle's radius and speed correspond to a frequency component. A trail traces the tip of the outermost circle, progressively drawing the target shape over one full revolution.
