Description
Generates an infinitely-scrolling sequence of dazzle camouflage patterns. Dazzle Ships were military
vessels during World War I and early in World War II that were painted not to conceal but to confuse:
with these Cubist overlapping stripes, it was very hard to estimate their size, range and heading. This
was a big deal before the invention of Radar.
