Artist’s construction and exhibition account.

Visitors move the monumental structure

Zachary Coffin dates Colossus to Burning Man 2005 and describes a sculpture nearly seventy feet tall. Pull ropes rotate its three rocks, central head and spires. His page also records a subsequent Bay Area Maker Faire installation without specifying its year. The interaction links a very large silhouette to a simple action that visitors can understand.

A focal point for the city center

Burning Man’s 2005 retrospective places Colossus in the Keyhole above Center Camp. It describes moving boulders suspended from metal arms and credits the sculpture with anchoring that central space. This is a placement precedent for combining a distant landmark with close participation.
