Anotations

Scope note:

Animation technique invented in the mid-1930s by Alexandre Alexeieff and Claire Parker, in which a vertical metal surface is perforated by millions of holes into which headless pins are inserted; the pins are depressed to make shadows, and changes in the position of the pins are filmed frame by frame, creating an animated effect when projected at normal speed.
