A spirograph is a geometric drawing toy that produces intricate and beautiful designs known as spirographs. It consists of a set of plastic gears and a pen. By placing the pen in one gear and moving it around another fixed gear, users can create a variety of patterns and shapes. The designs are often circular and can be quite complex, depending on the arrangement of the gears. Originally invented in the 1960s, the spirograph has become a popular tool for both children and adults. It is often used in art and education to explore concepts of geometry and symmetry. The resulting artwork can be used for decoration or as a basis for further artistic projects.
