GoKawiilBlog post explains drawing shapes like a llama using Fourier epicycles
A technical blog post walks through how the Fourier transform can be used to reconstruct a hand-drawn path, such as a llama, by summing rotating vectors (epicycles) of different frequencies, radii, and starting angles connected tip to tail. The author shows progressively complex examples, from a straight line and square to a fish, culminating in a llama drawn using 1024 circles.
