This is from a fascinating exhibition currently at MoMA. The artist arranged all of the items in his mother's home. He collaborated with his mother on laying it all out. This is a shot of a portion of his mother's home with many colorful shopping bags laid out as a continuous surface; in the gallery, the frame of the house is supported by sections of tube & clamp scaffolding. It is interesting because in a typical construction scenario it is usually the scaffolding that relies on the original building structure for stability. Scaffolding itself doesn't resist lateral loads very well, so it needs to be tied back to the main structure for support. In the case of this structure, the original building needs the support of the scaffolding, almost as a prosthetic, to stand.
