Spirograph Drawing Screensaver
The Spirograph Drawing screensaver traces the classic gear-driven spirograph pattern continuously, with looping curves in shifting color. It is free, runs in your browser, and ESC exits.

How the Spirograph Drawing screensaver works
The saver computes the real hypotrochoid/epitrochoid curve math behind the classic spirograph toy.
A small circle rolls around a larger one, tracing a looping pattern as it goes.
The gear ratio slowly drifts over time so the pattern never repeats identically.
Colors shift gradually along the curve for a flowing, hypnotic effect.
A worked example
As the rolling circle completes one lap, a fresh looping curve overlays the last, gradually building a dense, symmetric flower-like pattern.
Settings & tips
- Accent sets the base curve hue.
- Based on the real hypotrochoid math behind the classic toy.
- The gear ratio drifts slowly so patterns never repeat exactly.
Frequently asked questions
- Is this based on real math?
- Yes — the real hypotrochoid/epitrochoid equations behind the classic spirograph toy.
- Is a key needed?
- No — it is a pure local animation.
- Is it free?
- Yes — free, no download, in your browser.
- Does the pattern repeat?
- The gear ratio drifts slowly, so exact repeats are rare.
