Origami Skeleton by Marc Kirschenbaum

It's marvelous what you can do with a simple piece of paper. Marc Kirschenbaum is an advanced origami artist and has created this skeleton from a single square. He put all the instructions and diagrams in a document of fifteen pages and ninety-three illustrations, that you can find at his web page. But you really have to master origami before trying a big catch like this one!
