All aspects of any space utilized by humans can have a spiritual component it conveys, whether home, an office, a building, a hospital, a religious space, even an outdoor environment. I have used all as my personal canvas at some time or other, including the stoles worn by religious conveyors. Each being quite contemplative in a restful way, perhaps stretching the mind to think or just plain relax and let go. One seminary in Minneapolis has added a degree program just for this purpose, thus realizing the importance of art in these settings. 

One hospital series focuses on healing the mind, another on the importance of organic chemistry in solving medical problem into the future.
