Reynaud devised the Praxinoscope, patented on 21 December 1877, a cylinder with a band of coloured images set inside. There was a central drum of mirrors, which were equidistant between the axis and the picture strip, so that as the toy revolved the reflection of each picture seen in the mirror-drum appeared stationary, without the necessity for complex stop-start mechanisms. The images blended to give a clear, bright, undistorted moving picture without flicker. With his mother he took an apartment at the Rue Rodier in Paris, using the adjacent apartment as a workshop where the Praxinoscope was commercially produced, receiving an Honourable Mention in the Paris Exposition of 1878.
The Praxinoscope incorporates the principle of William George Horner's Zoetrope, using a removable strip printed in a series of 12 drawings that makeup a cyclical movement. As the cylinder rotates, stationary mirrors in the center reveal a ‘single image’ in motion. This strip is placed inside a drum rotating about an axis used as a base.
