Spirographics

Spirographics are interesting circular designs which were drawn using a Spirograph in the old days before computers, but which can be drawn with computers now. Not all the circular designs in this collection are actually spirographics, but they are circular and a similar technique is used to make each pattern in this collection. Check out the designs by pressing number keys one through six and watching each pattern take shape. Also inspect the code and work hard to understand how these things get drawn.

ASSIGNMENT:

Your job is to alter the demo project in the following ways:

  • Change pattern four so that small triangles are drawn at the end of each arm instead of small circles.
  • Alter the code for pattern four so that each arm and the shape at the end of the arm is a different color.
  • Create a seventh pattern of your own creation.
