The other day I installed new brake rotors on my mountain bike . They are beautiful; every scrap of stainless steel not required to withstand structural stress and the build up of heat has been removed. A laciness which could be mistaken for decoration is no more or no less than the result of form following function. As a chain is a chain and a tire inexorably a tire, so the rotors would cease to be themselves were they square or triangular, made of concrete or glass.
Architecture is not like this.
