Draw a closed loop with your finger or Apple Pencil or upload a picture or of a silhouette or SVG file and I will transform it into a Fourier epicycle squiggle using the complex Fourier series!
Features:
 • Import SVG files
 • Import Images of silhouettes
 • Copy the Fourier equation coefficients (initial angle and radius)
 • Save pictures of your squiggles to your photo library
 • Change the thickness and colour of the outline
 • Use up to 500 epicycles to approximate outlines
