Repetition in design seems to satisfy something in us. If anyone has an idea about what it is, please comment. I know the feeling from the inside, but I’d be hopeless at trying to explain what it is that repetition does to me. Maybe it is the regularity. Maybe it implies continuity – and we like that because it is soothing, like the sound of a train’s wheels on the track. The world is unpredictable and we try to add a degree of predictability to it (and a soupçon of unpredictability to keep up our interest). Perhaps theses are all something to do with it, but the words are as far from the feeling as ducks from an architect.
