This interactive tool visualizes how a smaller planet orbiting a larger one, which itself orbits a star, creates complex mandala-like curves called epicycloids.

Why it matters: It reveals beautiful mathematical patterns arising from simple orbital mechanics, blending science and art.

The big picture: Changing the ratio of orbital speeds generates diverse shapes, demonstrating the link between motion and geometry.

Quick takeaway: Users can customize parameters and embed these dynamic planetary patterns directly into web pages using simple HTML.

Commenters say: Many appreciate the visual appeal and educational value, with suggestions for adding more customization and detailed explanations.
