The sculptures, called Massimals, a play on the architectural term massing, are by Jason Scroggin, an associate professor of architecture at University of Kentucky College of Design. He says he wanted to use three-dimensional modeling techniques to build something “big and engaging” that was “abstract but recognizable.”

“I want people to hug architectural form,” said Scroggin. “While I enjoy presenting the Massimals in a museum or gallery context, they really want to mingle with people in the public realm. I think the Pedway is a great space for them to hibernate and bring a little color and playfulness to people moving through the underground spaces during the colder months in Chicago.”

Chicago Loop Alliance sees them as a way to promote the Pedway as “more than an underground route from A to B.”

“Chicago is known for amazing public art,” said CLA Director of Planning Kalindi Parikh. “There’s no reason the Pedway can’t play host to it.”

Massimals in the Loop will debut on December 20 in the Pedway below Daley Center, Macy’s, and other locations. The project will last through winter.
