The Dot and the Line - Chuck Jones

Chuck Jones has done very well to represent the mood of the characters, despite them only being simple shapes without facial expressions...

For example, the line thickens slightly as he breathes in and out, and as the dot insults the line the background closes in on him, showing a sense of foreboding and darkness being thrust upon him as his dreams are crushed; It's little details and movements such as these that give even simple shapes a sense of character and feeling.

It works really well with the music, since in parts it seems as if the shapes are dancing to the music and bouncing at exactly the right moments, and the change in beats and rhythm represents the mood of the story.
