The light is, on the one hand, curious and sets out to find the person but gets shy when the person comes closer. When the person directly looks at it, the light turns off. The light cannot see the person, as it needs its own light for a webcam to detect the person. In addition, the person will not see the artefact that well in this situation. To try and see if the person is still there, the artefact has to turn on its light or it can move and dare to look in another direction. The webcam turns along with the light, and sensing and acting are embodied.
