Water Ways Illusion

Here is another excellent creation by Aiyoshi Kitaoka he is a master of the art. In the below optical Illusion the black and blue columns actually are all perfectly straight and intersect at 90 degree angles.

"Waterways"

Waterways appear to tilt alternately, though they are parallel to each other. Moreover, "water" appears to swing in the horizontal directions.
