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:
“in the mind of man,
A motion and a spirit, that impels
All thinking things, all objects of all thought,
And rolls through all things.”
—William Wordsworth (1770–1850)
“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)
