Norman Wilkinson, Dazzle Camouflage for WWI + WWII Ships, c. 1917-45 (via ninakix; paperarchitect)
“At first glance Dazzle seems unlikely camouflage, drawing attention  to the ship rather than hiding it, but this technique was developed  after the Allied Navies were unable to develop effective means to  disguise ships in all weathers. Dazzle did not conceal the ship but made it difficult for the enemy  to estimate its type, size, speed and heading. The idea was to disrupt  the visual rangefinders used for naval artillery. Its purpose was confusion rather than  concealment. An observer would find it difficult to know exactly whether the stern  or the bow is in view; and it would be equally difficult to estimate  whether the observed vessel is moving towards or away from the  observer’s position.”
