Working Cardboard Mechanical Plotter By Norman Chan Niklas Roy's amazing new project is a working mechanical plotter made out of cardboard, rubber bands, wire, and glue. "The digital memory is a little book with plenty of different drawing codes, which are written down as coordinates. In this video I'm entering the first code, which makes the plotter draw "hello world"." This isn't the first time Roy has built a functioning machine out of cardboard, either. Here's the cardboard computer project he led at the School of Art and Design in Offenbach.
