Between the Lines

Between the Lines is a long row of "lightsticks" hanging from the ceiling. These lightsticks are actually a computer-generated pattern of red, yellow and blue lights programmed to produce a specific moving image. When you sweep your eyes across a blinking pattern, the light-sensitive layer at the back of your eye (the retina) retains what you see for a fraction of a second. This process—called persistence of vision—make it possible for you to connect the pieces and see a whole image.
