Believe it or not, Delphus, the mask pictured above, is folded from one solitary sheet of elephant hide paper (don’t worry, no elephants were harmed or used). Delphus is just one of Joel Cooper’s incredible origami creations. Check out more of his work on his Maker’s Market page, which includes a tutorial on making a grid, the foundation for making mind-blowing paper tessellations. You can also see more of his work on his Flickr stream. Below is Alberich, also meticulously folded from one single, uncut piece of paper. Stunning.
