The narrator asks us to 'turn' ourselves, slowly. Hidden in the scattered lines that illuminate the page is the image of an insect's wing.
The lacewing is a shortlived insect that I have used as an image of the 'insignificant traveller'. Something negligible, whose journey nevertheless has its role in things, and which (like in the famous 'butterfly effect') can have consequences for larger scales of event. The evanescent, filament thin touch of human contact can seem so insignificant, but can mean worlds.
Blink, and you may miss it.
