Hundreds of lights run along tracks continuously. Varying orders create a continuity that overlaps in the space. Continuity due to varying systems overlaps in space. 

Each running light is completely autonomous and runs continuously, only aware of its surroundings, changing speed and occasionally stopping to replenish energy. There is no light that can grasp and control the whole.

When a person comes close to a running light, the light sometimes changes in speed, fades, or changes color and emits a tone. The surrounding lights respond and change to the same color.

When people are not close by or at certain times, the running lights slow down and begin to blink slowly.
