Fourier portrait
A single closed line traced from my photo, redrawn by rotating circles. Each circle spins at a fixed speed; chained tip to tail, their sum draws the face.
Move the slider to change how many circles are used. Fewer circles give a blurrier line, and the error figure shows by how much. Press Draw your own and drag inside the frame, or Use your own photo: its outlines are traced and redrawn by circles.

Your photo stays on your device. It is traced inside this page, never uploaded, never saved, and gone when you leave.
