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
processcalled persistence of visionmake it possible
for you to connect the pieces and see a whole image.
