These incredible rulers by the same artist who created our CineSpinners make fantastic gifts for any occasion. Simply tilt the ruler up and down to observe the eye opening and closing.

When suspended from a string and spun slowly, these optical illusion spinners give the illusion of motion. As the spinner turns, the spacing between parallel sets of vertical lines on one side of the disk allows different sets of lines on the other side to show through in sequence. This is often referred to as "picket fence" animation.
