Dazzletesting

John Graham Kerr, a zoologist specializing in the embryology of lungfishes, in 1914 proposed to the British Navy that they paint their ships in black and white stripes as a camouflage. Testing was done demonstrating limited success but further research discovered that ships painted with random geometric patterns were harder to track for distance, direction and speed.  This scene must show some early tests of dazzle camouflage using model ships, 

Apparently the man on the right is peering through a device that simulates a submarine periscope to try to estimate speed and direction.  Reddit.  

The bartender on the left is hoping business will improve. (Mr G.)
