Geometry is the way we describe the glue that binds together our world. Geometry is the language of physical structure. Geometry encompasses the principles that define relationships between points in space (or objects in space, or locations in space).

From Wikipedia:
Hex signs are a form of folk art, thought by some to be of a talismanic nature[citation needed], found in the Fancy Dutch tradition in Pennsylvania Dutch Country.
Artfully painted hexagonal star-like patterns are a well-known sight on Pennsylvania Dutch barns in and around central Pennsylvania, especially Berks County. However, the decoration of barns is a late development in Pennsylvania Dutch folk art. Prior to the 1830s, the cost of paint meant that most barns were unpainted. As paint became affordable, the Pennsylvania Dutch began to decorate their barns much like they decorated items in their homes. Barn decorating reached its peak in the early 20th century, at which time there were many artists who specialized in barn decorating. Drawn from a large repertoire of folk designs, barn painters combined many elements in their decorations. The geometric patterns of quilts can easily be seen in the patterns of many hex signs. Hearts and tulips seen on barns are commonly found on elaborately lettered and decorated birth, baptism and marriage certificates known as Fraktur. In recent years, they have been increasingly used by non-Pennsylvania Dutch persons as talismans for folk magic rather than as items of decoration. Some scholars argue that they have never had any connection with superstition or magic[citation needed]. They are viewed as decorative symbols of ethnic identification, possibly originating in reaction to 19th Century attempts made by the government to suppress the Pennsylvania German language. In the 20th Century, mobile signs were produced as commodities. These signs could be bought and then mounted onto barns.
