The name alludes to traditional origami, which is the Japanese art of folding flat materials, generally paper, into figures resembling various objects. Other examples of moneygami include folding bills into clothing-like bits, such as dollar bills becoming bowties. [1]
The most common shapes created using foldforming are flowers, leaves or horns of a ram, as these require the repeated process of folding, annealing, unfolding, and hammering of sheet metal that foldforming also involves. The process of a flower unfolding or how a leaf forms is similar between natural occurrences and foldforming.
Geometric Origami is a book on the mathematics of paper folding, focusing on the ability to simulate and extend classical straightedge and compass constructions using origami. It was written by Austrian mathematician Robert Geretschläger [ de ] and published by Arbelos Publishing (Shipley, UK) in 2008.
Strip folding is a combination of paper folding and paper weaving. [30] A common example of strip folding is called the Lucky Star, also called Chinese lucky star, dream star, wishing star, or simply origami star. Another common fold is the Moravian Star which is made by strip folding in 3-dimensional design to include 16 spikes. [30]
The fold-and-cut problem asks what shapes can be obtained by folding a piece of paper flat, and making a single straight complete cut. The solution, known as the fold-and-cut theorem, states that any shape with straight sides can be obtained. A practical problem is how to fold a map so that it may be manipulated with minimal effort or movements.
A paper fortune teller may be constructed by the steps shown in the illustration below: [1] [2] The corners of a sheet of paper are folded up to meet the opposite sides and (if the paper is not already square) the top is cut off, making a square sheet with diagonal creases.
Modern origami has attracted a worldwide following, with ever more intricate designs and new techniques. One of these techniques is 'wet-folding,' the practice of dampening the paper somewhat during folding to allow the finished product to hold shape better. Variations such as modular origami, also known as unit origami, is a process where many ...
The fold-and-cut theorem states that any shape with straight sides can be cut from a single (idealized) sheet of paper by folding it flat and making a single straight complete cut. [1] Such shapes include polygons, which may be concave, shapes with holes, and collections of such shapes (i.e. the regions need not be connected).
