The San Lorenzo Colonnade, Milan. A group of shining bikes begins to wander the city, creating a ballet of light that winds through city streets which hours earlier had been bustling with traffic and now appear to have fallen into sweet sleep. Without meeting a soul, the bikes pass deserted squares, old courtyards, and landmarks in an increasingly metaphysical, unreal, and rarefied atmosphere. Thus opens an unusual image of a modern urban landscape which closes when the lights go out and everything falls back into darkness.
