Artists make functional objects and structures (buildings) more pleasible!

The above picture is of an unknown artist. The reason why I chose this picture (sidewalk art), is because right away I though of these kind of paintings that reflected how artists make use of functional objects. Here, in this example, the artists uses a functional walkway as their "artboard," and creates stunning pictures. Only viewable from certain angles will one get to fully engulf themselves into this experience. Similar to the African artist Kane Kwei, both utilize a structure and turn it into a work of art.
