Technologies like eye-tracking and mouse-tracking are increasingly being embedded in our interactions with devices, whether we realize it or not. As you observe the clouds in Megastructures, gaze-tracking technology follows where you eyes move. When you look away, the screen reveals the path that your eyes followed, although that image is no longer visible to you.
In observing the clouds, you become the object of observation by the machine, which traces and records your movements. What kinds of technology might be hidden behind our screens and what do they know about us?
