Spring Joint Flapping Crane

This crane design uses a corrugation called a Spring Joint to flap the crane's wings when it is pulled. The class will first be taught how to fold the Spring Joint corrugation, and then how to apply it to the traditional crane using grafting. The starting angle and motion of the wings can be customized based on the folding pattern.

Students should feel comfortable with origami pleats, be it through box pleating or corrugation folding, and should have experience with using precreases in collapsing steps.
