Abstract
This study aims examine systematically placed pattern using plane geometry. A square-unit pattern, which is methodically composed of the basic square-unit, shows some similarities to Moire Pattem when it is overlaid with the inverted square-unlt pattern. However, obviously the structure of above-mentioned pattern differs from the one of Moire-Pattern. It is possible to conjecture that the new-pattern system is closely parallel to the theory of "synchronization" in physics, for instance. Here we analyze the new-pattern system composed of the square-unit pattern in four ways of verification, and also introduce several interesting pattern that appear during the process.
