Twenty stainless steel cylinders rise from the bank of Willow Creek at the gateway to Mason City's Riverwalk, arranged in two curved runs. Inspired by a sound wave, pipe organ geometry for the form and a nod to the prairie school architecture of Frank Lloyd Wright.

Stainless steel with internal LED lighting.

The City of Mason City commissioned the work as part of the River City Riverwalk, with Group Creatives managing the project. It opened in June 2025.
