The origami crane diagram, using the Yoshizawa–Randlett system. The Yoshizawa–Randlett system is a diagramming system used to describe the folds of origami models. Many origami books begin with a description of basic origami techniques which are used to construct the models.
Sipho Mabona – Swiss and South African origami master [1] [6] who created a life-size elephant from a single piece of paper. [3]Jun Maekawa – software engineer, mathematician, and origami artist known for popularizing the method of utilizing crease patterns in designing origami models
Many modular origami models are decorative folding balls such as kusudama, which differ from classical origami in that the pieces may be held together using thread or glue. Chinese paper folding , a cousin of origami, includes a similar style called golden venture folding where large numbers of pieces are put together to create elaborate models.
Water Balz and Orbeez have been swallowed and lodged in the guts of children, requiring surgery to remove.
