"A quick change"
Something changes when one image changes to the other one, but it takes time for observers to detect it. This phenomenon is called "change blindness".

"Whiskers"
Whiskers appear to grow up quickly or return rapidly. This appearance depends on the line-motion illusion.

"Swings"
She appears to swing her hand repeatedly. This appearance depends on apparent movement with speed lines.

"Jittering eyes"
Both eyes are stationary but appear to jitter slightly after the motion of the other parts stop. My opinion is that this may be the visual jitter illusion.

"A demonstration of representational momentum"
Both eyes move rightward from the left hand, disappears, and then appear again at the same place as the position where they disappeared. "Representational momentum" refers to an illusion that the eyes appear to appear again at the left side from the position where they disappeared. (though I do not see so...)

"Goggly eyes"
Both eyes rotate clockwise and pause a little, which gives a goggly sensation.

"A girl of rotating blue eyes: a reversal"
Both eyes rotate clockwise for five seconds and pause for three seconds. In the pause, the eyes appear to rotate counterclockwise. This effect is the motion aftereffect.

"Wink"
The left eye appears to wink sometimes. This effect is the apparent movement.

"A girl of anomalously rotating blue eyes"
Both eyes appear to rotate along the gravity axis. This effect is an example of shape constancy.

"A girl of quickly rotating blue eyes"
Eyes appear to rotate quickly in any direction.

"A girl of blue eyes"
Eyes appear to rotate clockwise... (though I am afraid that the image is too small for illusion)
Image that is large enough for illusion
