@enginewitty happened past an old barn and stopped to make a photograph for me, as he knows I like old barns! I decided to edit the photo to remove the utility pole and power-lines, tweak the brightness and contrast, and do some creative editing. Here is the result:
It is rather common in the southern US to find a "quilt square" pattern painted on barns. Sometimes, they are purely a decorative embellishment, but sometimes they hold some historical significance for the area in which they're located. 
Quilt patterns on barns date back to colonial America. After the colonists became established and had spare income, they painted small patterns on the ends of the barns as a way to celebrate their heritage. [source]
In recent years, "quilt trails" have become a local phenomenon:
A quilt trail is a series of painted wood or metal, hung or free standing, quilt squares installed at various locations along a route, emphasizing significant architecture and/or aesthetic landscapes.

I am acquainted with a woman in this area who is an active part of the local "quilt trail" project. She told me years ago that in order to be considered part of the local "quilt trail," a committee must approve each proposed design before it is implemented to ensure that it has homogeneity with designs used on other structures. Also, the design must be executed in a particular size and "registered" as part of the official trail. The local trail does not appear on barns, but on other historic structures in the county, such as the very unique architecture of our local museum, and other similar buildings.
