This is a project that me and my friends built for school (UC Berkeley). Its made of lego mindstorms, scissors, and some scrap metal. With all things considered, I think it turned out alright. Not only does it fold your paper for you, it also cuts it. It would be the perfect accessory for a fancy, high-tech, Japanese bathroom! This video shows two test runs; the first run works well, while the second one could have gone a little smoother
