Wiz lines refers to the ways in which cartoonists and graphic artistsPeople who are engaged in a broad spectrum of visually led ideas and activities aligned to the expressive arts draw shapes and use shaped lines to illustrate or infer specific types of movement e.g. the movement of a figure or animal jumping, a club or hammer being swung, or the firing of a bullet from a gun.
More complex examples of multiple wiz lines are often used to draw explosions and concussions.
They may be accompanied with onomatopoeic words, referencing sounds e.g. Bang, Boom or Whoosh.
