article-1380342-0BC3FB9800000578-30_634x433I remember having a Spirograph when I was a child, unfortunately mine was second hand and didn’t have all of the bits but I still managed to create to interesting pictures with it. This one, is slightly bigger and works on the same concept. It uses two pendulums suspended from wooden towers which are connected to drawing arms and moveable joints. A ballpoint pen is mounted at the point where the pendulums come together. The pendulums are set in motion by hand and then the motion creates a picture on the paper.
