The most elegant designs often fade into the background, becoming invisible through their perfect functionality. Day to day life is scattered with the artifacts of unrecognized ingenuity — the comfortable grip of a vegetable peeler, the intuitive layout of a highway sign, or the satisfying click of a well-made light switch. These artifacts represent design excellence precisely because they don’t call attention to themselves or their creators. Who is responsible for them? I don’t know. That doesn’t mean they’re not out there.
