Ouchi Apparent Motion Illusion

If you look at the left (black/white) pattern you will probably notice that the vertical pattern in the center appears to move relative to the horizontal pattern in the surround.

This diagram was adapted from a design presented by a Japanese artist whose name is Ouchi.

If you see relative motion on the right pattern than you can conclude that the illusion also works with color patterns.

Perhaps not. It might be that if the lumiances of the red and green rectangles were equal then the illusion might not be as strong or prehaps would even disappear.
