Does this work in person, or only on video? Because it’s not unusual to get this kind of effect as a result of beating interference between the camera’s frame rate and some periodic motion, like the spokes on a spinning wheel.

This will work in person - you can do this with fan moving slow enough so that the blades aren’t a blur to the eye. You can convince yourself that it’s moving the opposite direction for a second or two.

I’m mystified as to “soften my gaze”. Sorry, it just stays hard like a boiled egg. Thousand-yard stares are mine.
But I can make the thing change direction. Just shift your attention from the centre of the wheel to one side or the other. Look at the left side - it spins to the right. Look at the right side - it spins to the left.
I have just been doing the Glasgow University “Perception Census”. They tried to hypnotise me. THAT didn’t work!
