Pinscreen animation
Pinscreen animation makes use of a screen filled with movable pins, which can be moved in or out by pressing an object onto the screen. The screen is lit from the side so that the pins cast shadows. The technique has been used to create animated films with a range of textural effects difficult to achieve with any other animation technique, including traditional cel animation.
Origin
The technique was invented and developed by Alexandre Alexeïeff and his wife Claire Parker in their own studio in Paris, between 1932 (first tests) and 1935, when Claire Parker registered in her own name the Brevet d´Invention nº 792340 at the Direction de la Propriété Industrielle, Ministère du Commerce et de L´Industrie, République Française, Paris 1935. They made a total of 6 very short films with it, over a period of fifty years. The films have short running time, because the device is difficult to use, and have a monochrome nature, due to the images being created using shadows over a white surface. Due to the poetic nature of the images produced and the quality of the film's animation, they won numerous awards over the years.
