Also called cel animation, traditional animation was the process used for most animated films of the 20th century. The individual frames of a traditionally animated film are photographs of drawings, which are first drawn on paper. To create the illusion of movement, each drawing differs slightly from the one before it. The animators’ drawings are traced or photocopied onto transparent acetate sheets called cels, which are filled in with paints in assigned colors or tones on the side opposite the line drawings. The completed character cels are photographed one-by-one onto motion picture film against a painted background by a rostrum camera.

                                      

Ballet shoes, or ballet slippers, are specially designed lightweight shoes for ballet dancing. Ballet shoes are soft shoes worn by ballet dancers until their bones are ossified and their muscles strong enough for them to use pointe shoes, which allow them to stand on the tips of their toes (en pointe). Male dancers almost exclusively wear soft ballet shoes, as they very rarely go en pointe.

A lapel pin is a small pin often worn on the lapel of a dress jacket. Lapel pins can be purely ornamental or can indicate the wearer’s affiliation with an organization or cause; for example, American Flag lapel pins became very popular in the United States, especially among politicians, following the terrorist attacks of September 11, 2001.
