This visual illusion is called motion aftereffect and if we wanted to translate it into Greek, we would call it a motion action. It's not a new discovery since it was first documented by Aristotle. When the human eye stares at a moving image for a period of time (in this case 10-20 seconds) and then looks at a non-moving image, the non-moving image appears to move in the opposite direction to the moving one.
You can do the same while you're out in nature. For example, if you find yourself in a waterfall, just look at the cascade for 20 or 30 seconds, and then turn your gaze to the rocks on the side or something. The rocks will look like they are moving in the opposite direction.
