A Plastic Bottle's Stair Dance 

A plastic bottle performs a stair dance*, hopping up and down, tapping off wild rhythms like a Broadway dancer. At first glance, the bottle seems to be simply trashed around by wind gusts. But as the dance intensifies, it becomes more and more apparent that the bottle is rebelling against the wind, not following it. Finally, the bottle leaps into a different space, which has gently revealed its presence more than once during the dance, but seemed so far from this bustle and flurry and the chiaroscuro on the concrete steps.
