Program:  Pretty Line Designs
Author:  Michael White (mikewhite314@gmail.com)

This program draws those neat curved line designs circumscribed in a circle.  I don't really feel like explaining how the program works, and it might be a little cryptic, but just choose a number of points to be on the circle and then choose one of the menu choices.  Play around with it, you'll see how it works, but it may be a little confusing at first.

Some tips:  only prime numbers produce symmetric designs.  When you have more than 11 points, it looks pretty bad (unless you choose to only draw one stage, and again, play around with it and you'll figure out what that means.
