The work, Brenner says, uses light to give the illusion of motion at night. Vertical plates of steel will function as louvers in a window shade, creating a sense of cadence as people pass the sculpture.
A blue line of LED light will appear to rise and fall as one goes by.
It’s designed to make the artwork interesting both for pedestrians and for riders in a moving car.
The sculpture will serve as a gateway for people crossing the bridge to enter or leave the south Evanston community.
The date for a dedication event for the piece hasn’t yet been set.
