This is another of my earlier designs. It uses a simple level shifter to create the back, and the legs are made in a rather John Montroll-esque manner. Fold two corners into the center before folding the rest of the model.
I may have designed this model in a dream. I recall stumbling out of bed and groping for a square of paper before folding out this model in a near completed state. The only thing that has changed is some of the shaping on the head.
