Chinese fireworks

Chinese fireworks or paper fireworks, also known by the French terms feux pyriques or feux arabesques, is a type of optical toy box that displays pictures with twinkling light effects. The pictures are printed or painted on paper, parchment or cardboard plates, and contain perforated elements. A wheel with a spiraling pattern on coloured transparent paper is made to rotate between a light source and the picture plates, causing the light that shines through the perforations to flicker and to change colour.
