Spirograph Home

Spirograph is the best Spirograph simulation software on earth. This interesting program is absolute fun because of its ease of use and powerful features that allow you to create astonishingly beautiful Spirograph patterns. No other Spirograph software gives you the flxibility and power that this cool program offers.

Spirograph is sure to be fun for both kids and grown-ups alike. Due to its simplicity of use, even the children of very young age can use it easily. You can create great drawings by just modifying different values with the help of your mouse or keyboard. Since images can be exported or copied to paint programs very easily, it can be used in combination with any graphics creation tool like Paint or Potoshop to create more advanced drawings and images.

Here is Spirograph at work (click to see the full size image):

A cool spirograph image

Setting different parameters to change the curves and patterns is made possible through a simple side panel which contains several buttons and input fields easily manipulated with mouse and keyboard.

Features

Major features:

  • Create Spirograph images and a few more not possible using the real toy
  • See image creation as animation
  • Export the created patterns to image files
  • Save your work for later use.
  • Work with multiple Spirograph patterns at the same time
  • Copy-paste the curves between different instances of the application.

Spirograph Math

The math behind Spirograph curves is both simple and elegant. All these amazing patterns are drawn using hypotrochoid and epitrochoid equations that can be manipulated in different ways.

To see the eqations in action right before your eyes, you can use our free Math Processor software. Using Math Processor you can manually define and create the patters, which will give you a better idea of how the equations actually work. For more details on how this could be done, visit this page.

One of our users has created some amazingly beautiful patterns using Math Processor's graphing module and has been kind enough to write a tutorial to help other users. You can see some really beautifuly pattern and read the tutorial in PDF form on this link:
