Zoetrope

Zoetrope is a device that allows set of drawings or pictures to create an illusion of a movement. It works on the same principles as the phenakisticope. Phenakisticope is the precursor of the zoetrope. 
Zoetrope from the late 19th Century

       It was invented by British mathematician William Horner, in 1834. It become revolution in history, in terms of animation, as it was one of first devices that created first animation movements. It didn't become popular until the 1860s, when it was patented by makers in both England and America. 

The images in zoetrope become ''alive'' when you place a strip of drawings inside the zoetrope's drum, spin it and look through the slots and the images will appear in continuous movement. This illusion of motion depends on the persistence of vision. 

Persistence of vision is a theory, which explains that the human eye always retains images for a fraction of a second (0.04seconds). This means that everything we see is a subtle blend of what is happening now and what happened a fraction of a second ago.

The negatives about the zoetrope is that if a person looks at it from bad angle the persistance of a vision can't happen anymore.



This is an example of my own zoetrope testing.
