                         traditional physical pinscreen image synthesis process. The basic 
                         goal is to enhance the artists ability to express themselves. 
                         Prinscreen is a very particular and difficult device that enables 
                         a chiaroscuro approach to image synthesis. In this paper we 
                         describe with some detail the traditional pinscreen technique, the 
                         way is operated, results and relates difficulties. A first basic 
                         computer model to simulate the pinscreen is presented. New 
                         important extensions to the basic model are also proposed. 
                         Advantages and possibilities of the method when compared with the 
                         traditional method and the problems that arise from this technique 
                         will also be explained.",
