Papel Picado is an art form from Mexico, but it is found in other countries, such as China and Japan, as well. The mathematics of symmetry is often involved in this art form. Not all creations are symmetrical, but the patterns that will be used in this module are symmetrical in nature. Here are some links to more information on paper cutting.
