Artistic Origami To the mathematicians and modern origamists origami is a puzzle. They see squares, triangles and rectangles that they can manipulate geometrically. They see competition as to who can develop the most intricate design. On the other hand the artistic origamists are more concerned with the figure's expressiveness and creativity. Origami construction is defined as the folding of paper using the raw edges, points of the paper and any creases or points subsequently created by those folds. The folded paper is seen as both an art piece and a geometric form. The folds produce varying sizes of triangles, rectangles and other shapes. This art form was passed down from generation to generation with nothing in writing. Due to all information being passed on orally, only the simplest designs were passed on. Around the year1797 the first written instructions appeared. The publication they were in was called the Senbazuru Orikata (Thousand Crane Folding). Origami also teaches children about problems solving and other aspects of mathematics that are relative to life. It also encourages children to set goals and work toward achieving them. Psychologists and physicians use origami as a therapeutic tool. It has proven to be successful in the treatment of mental health patients.
