There are two sides to every issue:
one side is right and the other is wrong,
but the middle is always evil.

"Packed rays"
Each ray is a square but appears to be distorted by the illusion of shifted gradations (Kitaoka, 1998). In addition, the eyes of the darker rays appear to be lighter than those of the lighter rays, but they are identical in luminance gradient. Moreover, some parts of the vertical or horizontal lines appear to be lighter or darker than other parts (Logvinenko illusion?).
