"A simple way to demonstrate the illusion of motion is to draw a line in the lower right-hand corner of each page of a pad of paper, altering the angle of each line very slightly in a single direction. If the pages are then riffled at a rather fast pace, the eye will perceive the illusion of a moving line."
What does it mean? Is it a curvy line or a straight line? Thanks.

Hello Elinor, Have you done the drawing?
I trust it is a straight line due to persistence of vision. I did flap-book before, it was fun to play with but surely lots of works there. Perhaps write a program to generate the simulations
