In human perceptual fields, priority of focus is given to change or motion. Therefore, the background would serve as a constantly moving display, changing, generative, to attact attention from far away. It would remain abstract to generate a sense of wonder or curiosity and draw someone in. Once near the display, the surface would sense a presence and react, indicating that you, the viewer, can influence or impact or participate in the display. Interacting with the display would be experiencing a brand, product, service or channel.
