Zigzag Way Illusion (Anh Pham edition)









In this illusion, there are two motions:
1. the blue rectangle moves in straight way
2. the background with black and white color rotates in one direction


if you look directly at the blue rectangle, you will persive it move straight and does not change its color. When you look at the red square, you will persive it moves in a zigzag way (the direction of the rectangle depends on the current rotation angle of the background) and its color changed brighter when moving in black areas and darker when moving in grey areas.


The motion of the rectangle and the background create two sources of imformation.
when we look at the display foveally, we can discern multiple features simultaneously but its quite different when we look at the display peripherally. It is hard for our visual system to analyse sources of imformation exactly.
The motion of the background is global motion and the motion of the blue rectangle is internal motion. It could be the global motion affects to the internal motion because the global motion has a stronger affection than the internal motion to the peripheral visual system.
