When the patterns and the grid are looking very organized/rigid, and logically placed, there is a certain boredom that comes with it.
As an artistic touch, I was thinking of the possibility of introducing some excitement into the regularity and predictability of a pattern, by breaking it somehow. (Breaking the Box)
The repetition of a pattern is like a classical elementary music (a fugue), and the mastery comes with the introduction of something different. Bolero is a very nice piece of music where repetition is apparent, but then its only one piece. The composition of many different harmonious pieces into a whole, requires a different kind of movement-The Magic Flute for instance-one which is full of surprises and keeps the audience engaged and wanting more.
Knowing where, when, and how to break the rules is the biggest part of artistry which makes Gestalt.
