Behind this form, a monochrome scene drawn in code: a starship adrift in three dimensions near a black hole, whose accretion disk streaks past in orbital arcs and whose far side is lensed over and under its shadow. The ship begins as dashed construction wire; each field you complete builds another part of it and brings it further into solid, photographed form, and moving your pointer near the hull inspects it with a work lamp. It is decoration — the form works completely without it.
