I came upon these great images while walking up Michigan Ave. The images change and represent the citizens of Chicago. I didn't know what to call these, there was no signage that I could find. I asked a local woman and she said they were called Spitting Faces. When I got home to Murrieta, I looked it up and the two towers are called Crown Fountain, designed by Spanish artist Jaume Plensa.
Go take more photos,
