Mathematica includes code to draw whimsical images like a dragonfly using Fourier series.
The dragonfly image is created by a parameterized curve expressed through Fourier series with frequencies up to sin(81t).
To draw such images, the number of Fourier components required depends on the smoothness and complexity of the image.
The process involves creating the image in software like Adobe Illustrator or Inkscape, then using a Fourier transform on a sample of the curve to generate the parameterized curve.
