The digital installations for the new David H. Koch Center for Cancer Care are designed around the feelings and needs of patients and caregivers. The main lobby hosts the welcome wall, Dreams in Fiber Optic Wood, featuring images in motion that glow directly through the wood of the building. Inspired by nature, the dreams include koi fish, butterflies, flowers and bonsai trees, all constantly changing with the seasons. The effect is deliberately meditative and atmospheric so that it can be viewed for one minute or one hundred. Because light passes through thousands of actual tiny holes in the wood, a special approach was required to create the original animated sequences.
