Frequently asked questions
What is a spirograph?
A spirograph is a geometric toy that uses circles rolling inside or outside other circles to create mathematical patterns called hypotrochoids and epitrochoids.
Can I save my creation?
Yes! Click 'Download PNG' to save the current pattern as an image.
Why do some values create closed patterns and others don't?
The pattern closes when the ratio R/r is a rational number. When it is irrational, the curve never closes and fills the space infinitely.
