Zoetrope

The Zoetrope, also known as the wheel of life was another optical toy invented around 1833 by William Horner. It is a cylinder with small slits at the top cut vertically, and a real of images down the bottom, or between the slits in a set sequence to show movement. When the Cylinder is spun, the same thing as the Thaumatrope occurs and the images seem to blur together creating an optical illusion of movement. 


Although the zeotrope we know today was invented in 1833, there is evidence that an earlier example of a zeotrope was invented in china around 180 AD by the inventor Ting Huan. Unlike the zeotrope we know, Ting Huans used translucent paper and was hung over a lamp, the air/heat rising from the lamp would then allow it to spin. Once spinning at the right speed the same effect would happen and the images would appear to move.
