Speed lines: Often in action sequences, the background will possess an overlay of neatly ruled lines to portray direction of movements. Speed lines can also be applied to characters as a way to emphasize the motion of their bodies [D 3]: 14 (limbs in particular). This style, especially background blurs, extends into most action based anime as well.
The particles are represented by the diagram lines. The lines can be squiggly or straight, with an arrow or without, depending on the type of particle. A point where lines connect to other lines is a vertex, and this is where the particles meet and interact. The interactions are: emit/absorb particles, deflect particles, or change particle type.
Squigglevision is a method of computer animation in which the outlines of shapes are made to wiggle and undulate, emulating the effect of sketchily hand-drawn animation. Tom Snyder of Tom Snyder Productions invented the technique, which his animation studio Soup2Nuts subsequently used in Dr. Katz, Professional Therapist in 1995, and in Dick and Paula Celebrity Special, the first season of Home ...
The Amsler grid showing the visual perception of the left eye of a person experiencing metamorphopsia (straight lines appear bent or curved) [1] [2]. Metamorphopsia (from Ancient Greek: μεταμορφοψία, metamorphopsia, 'seeing mutated shapes') is a type of distorted vision in which a grid of straight lines appears wavy or partially blank.
The drawing on the upper right shows a moiré pattern. The lines could represent fibers in moiré silk, or lines drawn on paper or on a computer screen. The nonlinear interaction of the optical patterns of lines creates a real and visible pattern of roughly parallel dark and light bands, the moiré pattern, superimposed on the lines. [4]

Flickering animation of a scintillating scotoma, where the scintillations were of a zigzag pattern starting in the center of vision, surrounded by a somewhat larger scotoma area with distortion of shapes but otherwise melting into the background similarly to the physiological blind spot
