Dust

Dust - it's everywhere and ever-present. A conglomeration of the finest particles set in motion as soon as things are starting to settle. It is fought and cleared away and yet returns again even as it is being removed. A Sisyphus is one who tries to defeat it. Dust nestles in carpets and in attics. It invades laboratories and settles on artworks. It is blown into the air from factory smokestacks and resides in every raindrop. Dust causes illness, dust makes up the cosmos. It is the smallest, discernable subject about which to make a film.
