Arithmetic Quilts combines mathematics and art. Addition tables, multiplication tables, and tables based on more complex operations are displayed as colorful quilts by assigning a specific color to each positive whole number. This makes it much easier to discover and appreciate the beautiful patterns of mod arithmetic. Quilts defined by a recursive process can also be created.
