The compositionalizing effort. Arrange space to offset it, call attention to itself. The metal protrusions that highlight a body, like earrings, piercings or halo pinned to your skull. There's an erotic element to piercing, allowing someone that access to your body, to puncture it, the gallerist's giving to the artist. Like Krebber making explicit his hesitation in painting in order to highlight (to absurd levels) the artist's consciousness, composition in sculpture is a game to highlight the object in an askew flatness, the thought that went into it, so can't forget about that ghost.
