I emailed Gordon but have not heard from him. I found a little info on Patterns in photography.
While repetition in the humdrum of daily life can at times be a little boring – capturing it in your photography can create an image with real impact.
Life is filled with patterns – many of which we overlook due to the business of our days – however once you get an eye for spotting them (and it takes being intentional and some practice) you’ll be amazed by what you see and you’ll wonder why you didn’t incorporate them into your photography before.

Patterns, both natural and man-made, bring a sense of visual rhythm and harmony to photographs that, like a series of repeating notes in a melody, capture the imagination. Patterns appear whenever strong graphic elements—lines, colors, shapes, or forms—repeat themselves.

Once you do become aware of the power of patterns, you will discover them almost everywhere: in a field of Maine lupines, in crowds of faces in a stadium, even in the zigs and zags of modern architecture. The secret to finding patterns is to explore potential subjects from a variety of angles. While you might not notice the colorful design of umbrellas as you maneuver a crowded Paris sidewalk, they become blatantly clear from an upper-floor window or balcony. Lighting is another potent painter of pattern. Fresh-plowed furrows in a cornfield, all but invisible on a dull, overcast day, rise into waves of highlight and shadow when lit by a bright, low-angle sun. Close-ups are also filled with pattern—consider the swirl of seeds in a sunflower or the intricate tracings of color in a butterfly's wings.
