"Most camouflage is based on the idea of concealment and blending in with its surroundings. However another school of thought has argued for making the item in question appear to be a mashup of unrelated components. Naval camoufleurs found this theory particularly appealing. Blending didnít work because ships operated in two different and constantly changing color environments - sea and sky. Any camo that concealed in one environment was usually spectacularly conspicuous in others.
Norman Wilkinson, a British naval officer and painter, suggested a scheme that came to be known as Dazzle or Razzle Dazzle painting. Wilkinson believed that breaking up a shipís silhouette with brightly contrasting geometric designs would make it harder for U-boat captains to determine the shipís course."

"Pioneered by the obsessive Dr W.S. Tucker of the Royal Engineers, the concrete sound mirrors were intended to provide early warning of incoming enemy aeroplanes and airships about to attack coastal towns.
But with the development of faster aircraft and the increasing racket from the holiday resort down the road, the effectiveness of the mirrors twindled as an aircraft would be within sight by the time it had been located. The last nail was finally driven into the coffin of this uniquely English folly by the evolution of radar systems, so by 1934 they had tragically became obsolete."
