History and Today:
The phenakistoscope (also spelled phenakistiscope or phenakitiscope) was an early animation device that used the Persistence of vision principle to create an illusion of motion. The Phenakistoscope is regarded as one of the first forms of moving media entertainment that paved the way for the future motion picture and film industry.
Although this principle had been recognized by the Greek mathematician Euclid and later in experiments by Newton, it was not until 1829 that this principle became firmly established by the Belgian Joseph Plateau.
The Special Honorary Joseph Plateau Award, a replica of Plateau's original phenakistiscope, is presented every year to a special guest of the Flanders International Film Festival whose achievements have earned a special and distinct place in the history of international film making.

Using different colors for the top/middle/bottom discs is important or you will not notice the effect. The more different the colors the better.
