A giant storage tank usually home to large quantities of the clear liquid toluene has been transformed into a daunting, rattling permanent installation by Zimoun. In the artist’s first permanent piece he collaborated with architect Hannes Zweifel to fill the towering tank—in Dottikon, Switzerland—with hundreds of balls attached to DC motors.

From the outside it looks like part of the industrial landscape, just a cylindrical tank sitting there abandoned. But inside the balls are pounding away at the white walls to create a dizzying perspective, as the camera peers upwards into the seemingly infinite soundscape.
