The word “design” has traditionally been used to describe the happy marriage of function and form. A chair can be comfortable and beautiful. An invitation can be clear and convey the personality of the event. Every object that serves a functional purpose can be made to not just work but be pleasurable to use and behold, representing the deep craftsmanship that we humans are capable of. But in this day and age, thinking of product design as form—as something purely visual—feels limiting.
