For some, dust is business, for some an obsession, for others merely something sloughed off, literally, into the environment. Even if we are not aware of it, we all participate in the subject of Dust. Whether it's a museum employee painstakingly keeping precious statues pristine, a housewife compulsively waging a weekly war in the cracks and crevices of her home, or the woman who finds innate beauty in the dust bunnies she mounts on her wall, Hartmut Bitomsky's fascinated film-through an ample and odd assortment of impassioned testimonials, interlarded with choice archival footage-investigates the myriad forms dust can take, how dust affects us, and how we affect it. Almost everywhere and always around, dust creeps into the corners of history as far back as the origins of the universe. And while dust from exploding stars can create solar systems, these same small particles can have devastating effects when they take the form of uranium fallout from U.S. weapons or the massive amounts of airborne debris that resulted from the destruction of the World Trade Center on September 11. As scientists study the harmful effects of breathing in this dust, and businessmen work to find ways to cleanse the compromised air, others are collecting and examining dust to learn about the past. Still others are so fascinated by the cyclical nature of dust that they look for ways to capture its beauty in art. Throughout, dust is relentless and persistent. Whether welcomed or not, it will no doubt always return.
