Specialized creative agency Leviathan has closely collaborated with the 900 North Michigan Shops to engage visitors with content displayed on a massive 190-foot LED digital art installation on its atrium ceiling. The Canopy, as it's known, is the digital centerpiece of a larger reinvention of this iconic Chicago retail destination. Visible from the street and all seven floors, the installation is a key element transforming the 30-year-old complex into a 21st-century attraction drawing retailers and customers alike.
