Zöllner lines

Parallel lines, usually three long ones, with a series of short lines drawn at regular intervals across one of the lines at approx. 60 degrees. Similar lines are drawn across the second line at the angle of approx. 120 degrees. Short lines are drawn across the third at the same angle as on the first lines. These lines produce the optical illusion that the long lines are converging or diverging.
