This work would incorporate windows or pigeon holes to work against the light produced by cutting and bending circular steel tabs from sheet steel. The “smoke” on either side of the structure is made from mangled weld-mesh. The horizontal central panel at the base includes overlapping strap-work of steel with over-stated rivets reminiscent of bridge building.
