COLUMBUS, OHIO.- The "second wave" of Mood River, the critically acclaimed contemporary design and art exhibition at the Wexner Center for the Arts, began in mid-April, when two portions of the exhibition are replaced by new work. Mood River, organized by the Wexner Center and curated by Jeffrey Kipnis, acting chief curator of exhibitions, and Annetta Massie, associate curator, reveals the aesthethic connections among more than 2,000 objects from everyday life. The show, previously scheduled to close on May 26, 2002, has been extended to June 30 by popular demand.
