In a class discussion of the phi phenomenon the other day, the talk
drifted around to stroboscopic phenomena, and the
"wagon-wheels-turning-backward" illusion that you get with films or TV.
I explained this briefly, but several of my students said that it didn't
depend on a flashing or intermittent source of illumination, as they
frequently saw this effect in broad daylight, on the wheels of moving
cars (especially those with wire wheels). I told them I didn't
understand how that could be.
Can you get this illusion under continuous illumination? How?
