Moth is a sculpture of contrasts. The material (marble) that Mac Adams chose is heavy and full of mass, but his subject (moth) is delicate and small. The work of art appears simple, but layers of meaning add depth and complexity. The moth itself, the focal point of the work of art, is in reality not present as a positive form at all, but is visualize through the negative spaces in the work of art.

Grace Hopper’s work the theme of this public artwork: She is credited with popularizing the term “debugging” for fixing computer glitches (inspired by an actual moth removed from the computer).
