Apparent motion direction changes: If the surround is sinusoidally rotating around the pitch axis while the center is physically rotating around the yaw axis (body axis of the observer) the rotation axis of the center is perceived as swaying with an apparent motion towards the right upper or lower corner.

The looming Duncker illusion:  An expansion or contraction of the surround by using a virtual zooming lens induces an apparent motion in depth of the center.

Asymmetry of the looming Duncker illusion:  Vice versa, the expansion or contraction of the center cannot induce an apparent motion in depth of the surround. Again, the looming of the texture was produced using a virtual zooming lens.
