gut rxn addresses permeability—the passing though—specifically in reference to the structure of intestinal lining, and the affects of its dissolution. Text and images oscillate through a membrane in mimicry of the digestive assimilation process. Discernible objects move through the membrane and eventually become distorted. The text, from a medical description of permeable membranes in the small intestine, moves in opposition to the images, from large, eligible markings into legibility.
