The interior was remodeled in 1995, adding to the lobby travertine and textured limestone surfaces. The elliptical-shaped plaza outside the building serves as a public oasis with seasonal plantings and a 12-foot (3.7 m) waterfall. A band of white lights at the top of the building is visible all over Chicago at night and changes colors for different events. For example, at Christmas time the colors are green and red. When a sports team goes far in the playoffs, the colors change, too. When the Chicago Bears made the Super Bowl the colors were blue and orange.
 

The building is a member of the World Federation of Great Towers. It also has won various awards for its distinctive style, including the Distinguished Architects Twenty-five Year Award from the American Institute of Architects in May 1999.
