Phenakistoscope

This was an early animation device that used the persistence of vision principle to create an illusion of motion. In 1832 Joseph Plateau created this device, it consists of two discs mounted on the same axis. The first disc had slots around the edge each one inch in measurment. When viewed in a mirror through the first disc's slots, the pictures on the second disc will appear to move. As a group we used the idea of a balloon rising into the sky, it was essential that all balloons were identical in size, colour and shape. Their position within each of their segments however did alter slightly to create the illusion. We had to also make sure each segment was exactly the same size.
