Sound artist Zimoun has completed work on what may be his most ambitious project ever—a towering sound installation inside an abandoned toluene tank in Dottikon, Switzerland.

The permanent installation uses 329 of the artist’s trademark prepared dc-motors and cotton balls that have been affixed to the inner tank walls, and relied on contributions from Hannes Zweifel Architecture, Davide Groppi, and many others. The result is a whirring, rhythmic soundscape that is completely camouflaged within an old factory.
Zimoun has completed several additional installations in the last few months, all of which can been seen on his website.
