In comics, motion lines (or movement lines or action lines or speed lines) is a term that refers to the abstract lines that appear behind a moving object or person to make them look like they're moving quickly. The use of motion lines may have been inspired from both mathematical vectors, which are used to indicate direction and force, and from long-exposure photography, where a camera can capture lights as they move through time and space, blurred along the direction of motion.
Famous quotes containing the words motion and/or lines:
“... The festival-colored brightness
That is their motion ...”
—Gwendolyn Brooks (b. 1917)
“When first my lines of heavenly joys made mention,
Such was their luster, they did so excel,
That I sought out quaint words and trim invention;
My thoughts began to burnish, sprout, and swell,
Curling with metaphors a plain intention,
Decking the sense as if it were to sell.”
—George Herbert (1593–1633)
