Baingio Pinna & Gavin J. Brelstaff Illusion
The new illusion is illustrated in bottom. In particular, the inner and outer rings of the concentric circles in picture appear to rotate against each other as the eye is moved continuously closer to the paper (looming) while the gaze is kept fixed on the central spot. Moving out again reverses the direction of the illusory rotation.
 
Focus your eyes on the center of the picture.
Draw close to the screen, then back again - the circle will rotate in opposite directions...
 
Parallel columns of the elements of opposite polarity
