Modified Cats Cradle

On March 5, 2015 I turned in this assignment using the knowledge we had learned in class about  if statements and for loops. Essentially all I had to do was modify a code we had already done in class. My previous blog post, "CSE Cats Cradle" is the code that I was expected to modify. Our assignment was is down below.

To exceed expectations, complete all 3. To meet expectations, complete 2. To approach expectations, complete 1.

1. Create a yarn art/cat’s cradle project that can color in the randomly created polygons.
2. Create a yarn art/cat’s cradle project where the points are animated and move around the screen with the lines stillCONNECTED.
3. Create a yarn art/cat’s cradle project where the user can move the points around theWINDOW by clicking and dragging them (the lines should still be connected).

I attempted to do all three of the assignments but was only able complete two, creating a cat cradle that could color in randomly created polygons and to create a cats cradle that had animated points that moved around the screen. Below is the codes I created.
