Origami isn’t just child’s play. It is a respected contemporary art form and an inspiration to scientists and engineers. Heck, the principles of origami were applied in the development of airbags for cars. “Folding Paper: The Infinite Possibilities of Origami” (Tuttle) by Meher McArthur, a curator of Asian art, and Robert J. Lang, a physicist turned origami artist, presents dozens of photographs of dazzling creations. The artworks run the gamut from representational (a dinosaur) to geometric (a spiked rhombic) and abstract. “Folding Paper” is a primer on the premier artists and the influence of this very old art form in modern research and design labs.
