WASHINGTON, DC.- The Smithsonian’s National Museum of African Art has launched the “Smithsonian: Artists in Dialogue 2” app for iPhone and iPod touch on the App Store. Designed in association with Tristan Interactives Inc. of Toronto, this is the first app available by the Smithsonian in English and Portuguese. “This app takes the exhibition beyond the traditional, physical boundaries of the building and makes it available in South Africa, Brazil and to users around the world using iPhone and iPod touch,” said National Museum of African Art curator Karen E. Milbourne. The exhibit “Artists in Dialogue 2: Henrique Oliveira and Sandile Zulu” will run through Jan. 5, 2012, and is the second in a series of exhibitions that connects artists by bringing them together to create site-specific works of art at the museum. In the exhibit, the artists’ visual call and response includes Sandile Zulu of South Africa’s trademark control of fire to create streamlined paintings and sculptures in
