Customize your spirograph then press start! Changeable variables include: 1. R, the radius of the stationary circle 2. r, the radius of the moving circle 3.O, the portion of the diameter the pen draws on (also when you make actually use it try turbo, as it can be slow.) ===========ADDED=========== Press 1-4 to change variables: 1: R 2: r 3: O 4: Multiplyer
Added the circles for visual effect(So you can see what is actually happening) Thanks @Flint-L for the pointing script
