You can't really see the third one well, but centered in the ring that seems to be floating on the box is another sculpture of three children playing on a jungle-gym. Every year my town puts out an exibition of public art scattered around the down town area. These are in a park near the center of town. The box in the front is actually not a sculpture, but an electrical box for the traffic signals. That's another cool thing about living here-- they have decided to let artists paint all of the signal boxes to make everything look nicer. So all around town are random bits of professional art! Pretty cool!
