Working out the intricate patterns in different projects can be quite tedious. Not just anyone will have the patience to continuously fold a piece of paper attempting to create a particular object. For people who design origami projects, the mathematics of it all can be very frustrating and again would definitely require a patient individual. Skilled origamists will take on projects such as elaborate ships, buildings, people and objects involving concentration and logical thinking. When people reach this level in origami, often they begin to design their own compositions. Individuals in this category might be considered origami artists and have their work entered in competitions and showcased at art shows and in art galleries. Buildings: Fumihiko Maki designed the Kirishima International Concert Hall. This hall was built using the architect's trademark brushed silver surfaces and was located on a secluded mountain site. In a style that resembled an origami figure the building had "folded" stainless steel planes that peaked into one of his "cloud" roofs. Origami as a hobby can be time-consuming if a person gets into the advanced forms of the art. Origami can begin as a hobby but turn into an obsession. Some people get so involved in their projects and developing their origami skills. Once they begin to design their own origami compositions, people find themselves entering contests and competitions to showcase their work. You want to be sure the children understand what they need to do and make sure you give them enough time to work it out themselves - don't jump in too quickly to help them. 6. Let them try to fix their own mistakes without too much assistance. Let them know they can "try again" as many times as they need. Mathematicians throughout time have developed ways to use geometry to define origami; they have designed highly sophisticated models using fundamental theorems. They have studied and found amazing similarities between tessellations and origami (tessellations is the name for a figure comprised of a shape that is repeated over and over again with no gaps or overlap when fitted to a flat surface).
