I heard this on a fuel cell podcast of Equis Financial. During WWI German U-boats were sinking as many as 50 ships a week. So, something had to be done. You could not camouflage a ship because the background is always changing. So instead, they tried to make the ship stand out in a confusing way. They would make it so you could not tell which side was the bow vs the stern. They call this Dazzle Camouflage. This is the Zebra idea. The torpedoes took as long as 3 minutes to get to their target and this messed up their aim as much as 60 degrees.

The point is some times you just have to think creatively out of a problem.
