• it works similar to Spirograph
• just load an example and click START

• a specific point (the handle) determines the path of the drawing point
• define your own circles with the mouse (click - drag - release)
• select a circle - it is active now (blue)
• create a new circle as a child(red) of the selected one
• enter the Spin and the Orbit Speed
• hold CTRL key for dragging the handle to a new position
• hold SHIFT key and click the handle to switch drawing on and off
• save and load your own creations
• if you create something crazy - send it to me - I will publish it
