The Zoa art piece surrounded by crowds in mid afternoon just as the fog was about to blow back in.

Up close the Zoa displayed many changing colors as it moved.

The Zoa was created by many pieces of plastic, carefully cut and heat sealed together.

Because of the many refracting colors, it was difficult to see a smaller, similar shape inside it.

Kids loved to spin the Zoa. It was so massive that it could only be spun slowly.

A walkway cover protected electric cables from shoes. Two signs were painted on that protector. The first credited "The Zoa @ Chromaforms," and the second warned "Do Not Climb."

The upper pivot of Zoa was held up by a cable suspended from a graceful arch.

Lace fabric covered the arch that held up one end of the Zoa art piece.

The Zoa art-piece from Chromaforms was located smack in the center of the fair. It was set up in the middle of the intersection of Howard Street and 2nd Street.
