Introduction
Spirograph is a geometric drawing device that produces interesting designs. Here we will write a program to do the same thing.

Project #1
Create an interactive program to draw spirograph designs
- ask the user for the spirograph R,r,d (integer) values
- draw points at the spirograph x,y coordinates (see the equations)
- save the starting x,y coordinates
- stop the program when it returns the starting coordinates
- start with angle = 0 and increment by 1° to draw points
Experiment with different input values.
Project #2
Ask the user how much to increment the angle each time when drawing a spirograph design.
Project #3
Draw lines rather than points.
FYI
Very fancy designs
