Merchandise Mart is making things special for Chicagoans this holiday season. As part of their holiday program, they are conducting Art on theMART.  There will be six winter holiday images that will each animate for a minute and a half, running in between the contemporary artworks by Diana Thater, Zheng Chongbin, Jason Salavon and Jan Tichy throughout the 2-hour program. The program is free and open to the public to view on Wacker Dr. or from the Chicago Riverwalk, Wed-Sun from 7-9pm.
