Paint the tiles above the color palette by dragging the left mouse inside the squares. Select a brush color by clicking inside the color palette. Double-click a tile to fill its entire area with a color. When you have painted the tiles, you can view the Cayley table or the quilt by using the View control at the top left (select Table or Quilt). The Operation control selects the operator used to make the Cayley table. The Quilt control selects the way the table is used to make the quilt.

See the diagram at the bottom of this page for a visual guide, and read about how the quilts are made in the "about" section. Explore the connection between the quilt patterns and clock arithmetic with the Clock Arithmetic demonstration.
