"Silencing is a new illusion that shows it's hard to notice when moving objects change."

"Instructions: Play the movie while looking at the small white speck in the center of the ring [of colored dots]. At first, the ring is motionless and it's easy to tell that the dots are changing color. When the ring begins to rotate, the dots suddenly appear to stop changing. But in reality they are changing the entire time. Take a look.

The same is true of changes in brightness, size, and shape."
