Triple-Eye Lightstick is an artist-in-residence piece you can only perceive in your eye. The lightstick consists of small, rapidly blinking lights which form patterns, but too quickly for your eye to normally see. The natural saccadic movement of your eye combined with your ability to retain images in your eye for a period of time allows your brain to perceive the patterns, even though your eyes can't, letting you see these fleeting images. The Lightstick can be programmed with different images.
