A Polargraph drawing machine is a machine that positions the drawing gondola by using a couple of cords. By doing that and controlling the drawing action it s possible to print an image much larger than conventional methods. Since a machine like this in action have a very high entertainment value, and combined with the ease of installation in different location, and a very big range of configurable sizes, it s a highly sought after attraction.
