Description

This online exhibit is a visual illusion in which a fuzzy blue dot disappears into a green background. The illusion is created by the tiny jittering movements that your eyes are continually making. Take your investigation further by making your own hands-on fading dot illusion - instructions are at the Exploratorium Snack website (see related link).
