Here is a phrase from Deleuze’s famous article “Difference and Repetition”. It clarifies my mind while thinking about patterns, boundaries, rules, and most importantly, the idea and techniques of deformation in contemporary architectural geometry.

… On the other hand, generality belongs to the order of laws. However, law determines only the resemblance of the subjects ruled by it, along with their equivalence to terms which it designates. Far from grounding repetition, law shows, rather, how repetition would remain impossible for pure subjects of law – particulars. It condemns them to change. As an empty form of difference, an invariable form of variation, a law compels its subjects to illustrate it only at the cost of their own change. No doubt there are as many constants as variables among the terms designated by laws, and as many permanences and perseverations as there are fluxes and variations in nature. However, a perseveration is still not a repetition. The constants of one law are in turn variables of a more general law, just as the hardest rocks become soft and fluid matter on the geological scale of millions of years. So at each level, it is in relation to large, permanent natural objects that the subject of a law experiences its own powerlessness to repeat and discovers that this powerlessness is already contained in the object, reflected in the permanent object wherein it sees itself condemned. Law unites the change of the water and the permanence of the river…
… If repetition is possible, it is due to miracle rather than to law. It is against the law: against the similar form and the equivalent content of law. If repetition can be found, even in nature, it is in the name of a power which affirms itself against the law, which works underneath laws, perhaps superior to laws. If repetition exists, it expresses at once a singularity opposed to the general, a universality opposed to the particular, a distinctive opposed to the ordinary, an instantaneity opposed to variation and an eternity opposed to permanence. In every respect, repetition is a transgression. It puts law into question, it denounces its nominal or general character in favour of a more profound and more artistic reality…
