Implementation is achieved as follows.
1. Select the number of vertices using the slider.
2. For each value of the slider 'skip', drag the slider 'first' through all of its values (this is accomplished most easily using the left-right arrows)
3. A colorful graph results when one occasionally changes the color of the first segment when 'skip' is incremented.
Students can be challenged to determine the number of segments for various values of N (number of vertices).
