Parallel Cafe Wall Line Illusion

Are these lines parallel?

The Gray Lines In This Illusion ARE Parallel!

Different parts of our eyes process colors at different speeds. Our eyes also react to light and dark colors differently. Because of the way the black and white tiles are lined up, the brain interprets the tiles are almost slanted in a way. Some people also believe that the gray lines themselves have something to do with it. When a gray line is between a white and black tile our eyes interpret the gray line as a part of the black tile.
