Iranian-born painter, installation and conceptual artist Taraneh Hemami has two homes -- and she also has none. When Hemami came to the United States in 1978 to attend the University of Oregon at Eugene, she had little idea of what the future held. Within a year of her arrival in this country, the Iranian Revolution had changed her homeland forever and prevented her from visiting for more than a decade. Spark follows Hemami as she gathers footage, photographs and stories from a Castro Valley Iranian woman named Nosrat, who is known as "Mommy" and whose life is the cornerstone of Hemami's multimedia display exploring the layers of history and connected stories within a family home. The finished product is an exhibit she titled "Homes," which was displayed at ZeroOne San Jose: A Global Festival of Art on the Edge and the Thirteenth International Symposium of Electronic Art in August 2006.
