Kaleidogami (IMAGE) Purdue University Caption This graphic illustrates the creation of morphing robot-like mechanisms and shape-shifting sculptures from a single sheet of paper in a method reminiscent of origami, the Japanese art of paper folding. The robotic and artistic designs are made up of building blocks called "basic structural units," or BSUs. Each BSU contains two segments joined by a creased hinge, and many BSUs are linked together to create larger structures.
