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:
“Two children, all alone and no one by,
Holding their tattered frocks, thro’an airy maze
Of motion lightly threaded with nimble feet
Dance sedately; face to face they gaze,
Their eyes shining, grave with a perfect pleasure.”
—Laurence Binyon (1869–1943)
“Your letter is come; it came indeed twelve lines ago, but I
could not stop to acknowledge it before, & I am glad it did not
arrive till I had completed my first sentence, because the
sentence had been made since yesterday, & I think forms a very
good beginning.”
—Jane Austen (1775–1817)
