The basic idea of these sketches is that they are careful implementations of a very precise experience. They are not complete implementations of a full system, which is why we call them sketches. These sketches or implemented experiences are such that they can be applied in many different ways. What makes them different from other sources of design inspiration is that they are grounded in the digital material, they are possible to implement and they work in harmony with the digital material. But not only that, they are design ideas that spur from combinations of the characteristics of the digital materials and the characteristics of aging. We argue they are design ideas that would not have happened if it were not for the specific combination, between one of the digital materials and the concept of aging and change over time. These sketches embody how some activity changes and age over time.
