In 1876 he decided to make an optical toy to amuse a young child. Improving on the Phenakistiscope and Zoetrope, Reynaud devised the Praxinoscope (patented December 1877). Consisting of a cylinder with a band of coloured images set inside, a central drum of mirrors was set exactly equidistant between the axis and mirror drum. As the toy revolved the reflection of each picture seen in the mirror drum appeared stationary. The images blended to give a clear, bright, undistorted moving picture without flicker. He produced the praxinoscope commercially, receiving an Honourable Mention in the Paris Exposition of 1878.
