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:
“No motion has she now, no force;
She neither hears nor sees;
Rolled round in earth’s diurnal course,
With rocks, and stones, and trees.”
—William Wordsworth (1770–1850)
“I need not tell you of the inadequacy of the American shipping marine on the Pacific Coast.... For this reason it seems to me that there is no subject to which Congress can better devote its attention in the coming session than the passage of a bill which shall encourage our merchant marine in such a way as to establish American lines directly between New York and the eastern ports and South American ports, and both our Pacific Coast ports and the Orient and the Philippines.”
—William Howard Taft (1857–1930)
