What are we looking at? We can perhaps discern from the greyscale fuzz, the varying degrees of white patches, fanning out from a point in shapes hard to parse, that this is an ultrasound display. But what are we trying to see in the scan? There is no baby or foetal development, no heart, no kidney, no liver, no needle to pierce through the night like a ship. But it moves in time with a voiceover. A mouth, surely? Yes. We are, quite literally, mechanically, watching someone speak.
