In this image by Aiyoshi Kitaoka the coloured bands of ‘water’ are parallel, I assure you.

Optical Illusions
Optical illusions (also called visual illusions) are characterized by visually perceived images that are deceptive or misleading. The information gathered by the eye is processed by the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are two main types of illusion - physiological illusions that are the effects on the eyes and brain of excessive stimulation of a specific type - brightness, tilt, color, movement, and cognitive illusions where the eye and brain make unconscious inferences.

Physiological Illusions
Physiological illusions, such as the afterimages following bright lights or adapting stimuli of excessively longer alternating patterns (contingent perceptual aftereffect), are presumed to be the effects on the eyes or brain of excessive stimulation of a specific type - brightness, tilt, color, movement, etc. The theory is that stimuli have individual dedicated neural paths in the early stages of visual processing, and that repetitive stimulation of only one or a few channels causes a physiological imbalance that alters perception.
Cognitive Illusions
Cognitive illusions are assumed to arise by interaction with assumptions about the world, leading to "unconscious inferences", an idea first suggested in the 19th century by Hermann Helmholtz. Cognitive illusions are commonly divided into ambiguous illusions, distorting illusions, paradox illusions, or fiction illusions.

Ilusión! Puedes creer que estas lineas azules son paralelas? [IMG]…
Nuestro cerebro realmente nos engaña…. Os aseguro que estas lineas son totalmente paralelas….

Si clavas/fijas la mirada en un cuadro blanco de esos, y observas de fondo 2 lÃneas azules, a los 2 o 3 segundos corrigen su forma y se vuelven paralelas.
Curioso.

Las figuras de color negro, muestran ubicacion invertida en cada fila, entonces las figuras azules que estan dispuetas horizontalmente, parecen tomar esa direccion.
Muy interesante el efecto.

@alejandro Supongo que también se debe a los cuadraditos pequeños en negro y en blanco que están girados no?

This is one of the best of this type of illusion I’ve ever come across. It takes a lot of effort to see the blue bars as parallel! Whoever created it: Nicely done!
