Mendi Lewis Obadike, a PhD candidate at Duke University, uses minimalist coding to convey painful silences that are in fact powerful statements -- it's a strategy that references work by black feminist artists and writers such as Faith Ringgold and Audre Lorde. "Keeping Up Appearances" (pictured) is the latest installment in Obadike's "Black.net.art" series. Her media art will be featured in the show "Only Skin Deep" at the International Center of Photography next year.
