Japanese artist Takayuki Hori created a lovely series of origami animal figures with printed skeletons. When displayed under the right light, they look like folded x-ray images. Here's how he does it:
each translucent sheet is first printed with either the images of fragments of an animal's skeleton, or, on some pages, human-made discarded objects that are often ingested by the animals in the wild. using the ancient tradition of folded paper, hori assembles the pages into a three-dimensional model. once the paper is folded, the printed components are united as a whole, telling the visual story of the animal's plight to survive in an increasingly polluted and hazardous ecosystem.
