Reality is as it changes, and flexibility in art is a visual likelihood of a thing's changing in space, while remaining what it is. As a stem of a flower sways in the wind, we have a sight of flexibility. Yieldingness as sight is much in pictures; the yieldingness that makes for strength is what we look for in art.

Furniture is the most common example of functional art. Well crafted furniture - tables, chairs, lamps or lights- have been collected for many years not just for its form and design but also functionality.

This type of art is also a sustainable art form. Since they are designed to be used, they are less likely to be thrown away or discarded. They are made to last and can be passed down from generation to generation. This is why functional art pieces are often considered to be heirlooms.
