Now it is, in fact, a children's toy, consisting of a plastic plate with circles of various diameters cut into it, as well as a whole additional set of gears with holes inside. The device was invented by engineer Denis Fischer in the 60s of the twentieth century for personal needs - at that time he was developing fuses for aerial bombs. The invention did not help him much in this task, but his family appreciated it as a convenient device for drawing. The scientist decided to patent the spirograph and launch its mass production. Since then and to this day, a simple, but at the same time very effective device, striking with an incredible combination of mathematical accuracy and art, enjoys stable popularity all over the world among people who would like to learn how to draw.
