                      CAYLEY QUILT MAKER


  Dr. Laurie Burton, Mathematics Department at Western Oregon
  University, has developed a mathematical lesson using clock
  arithmetic to create math art posters. Students can create
  colorful posters based on modular arithmetic operations
  tables by painting their own pattern replacements.

  The applet by Scott Lopez includes several presentation
  options including:

     - reflection
     - rotation
     - Fibonacci
     - D4 table
     - golden rectangle
     - color addition
     - parallelogram

  Students can select the number of tiles, fill any tile
  background, and vary the painting pen width and/or color.
