Five nights a week, a 25-story-tall video installation takes over the side of the Merchandise Mart, filling the building's historic facade with vibrant colors and moving images. Harnessing 34 digital projectors, the show features work by a rotating lineup of artists and is best viewed from Wacker Drive or the Riverwalk, between Wells and Orleans Streets. Art on theMART lights up the night Wednesday through Sunday, from 7:15 to 9:15pm.
