What does the interactive artwork Crown Fountain feature?

Crown Fountain, located in Millennium Park, features photos of Chicago citizens as a central element of its design. The artwork consists of two large, glass-block towers that display digital video images of local residents' faces, which are sourced from the diverse population of the city. Water flows from the mouths of the projected faces, creating a playful interaction that connects the community to the artwork. This engagement not only celebrates the individuals featured but also emphasizes the collective identity of Chicago's residents.

The other options, while they may involve artistic concepts relevant to other artworks, do not accurately describe the focal point of Crown Fountain, which is uniquely about the representation of real people from the city.
