The most expensive piece featured in Sculpt Siouxland this year, Zeller said it is also the largest sculpture she has ever made. The Plunge happened by accident when she was creating a 27-piece sculpture of the human form. "I had the lower torso of the piece sitting on the workbench and said, 'Ah, my figure is plunging into my workbench.' That was actually the inspiration for this big piece."
