Stick figure

A stick figure is a very simple drawing of a person or animal, composed of a few lines, curves, and dots. In a stick figure, the head is represented by a circle, sometimes embellished with details such as eyes, mouth or crudely scratched-out hair. The arms, legs and torso are usually represented by straight lines. Details such as hands, feet and a neck may be present or absent, and the simpler stick figures display an ambiguous emotional expression.

Graffiti of stick figures are found throughout history, often scratched with a sharp object on hard surfaces such as stone or concrete walls. Stick figures are often used in sketches for film storyboarding.
