Looking for a mental escape from New York’s unending heat wave? Each night at 11:57, Korean-born artist Elly Cho’s black-and-white video projection of breeze-rippled trees-at once restful and spectacular-reigns briefly over the colorful cacophony of Times Square. Shown on multiple giant screens, the work is drawn from the “Visual Kinematics” land- and seascape series by the 38-year-old artist, who holds graduate degrees from both Columbia University and London’s Slade School of Fine Arts.
