Katz Plaza Fountain and Eyeball Benches. It is located at 639 Penn Ave (Penn Ave and 7th St) Downtown, Pittsburgh PA. It was installed from 1996-1999 and is made of bronze, fiber optic lighting and granite. It has a 25 foot high fountain that has heated water. Surrounding the fountain are three different pair of benches in the shape of huge eyes. I chose this piece because it is unique and inviting for people to come and see the art, and even sit on the art. I also enjoy that it is in a public place where people can just walk by and see it.
