image: The experimental setup used to project grayscale light patterns into a glass container of polymer material. The light created a polymer film with stress patterns, causing the structure to fold like origami. This material relates to a paper that appeared in the April 28, 2017, issue of Science Advances, published by AAAS. The paper, by Z. Zhao at Peking University in Beijing, China, and colleagues was titled, "Origami by frontal photopolymerization." view more
