This old metal fence sitting atop a low stone-capped brick wall illustrates of the power of diagonal lines. They move across the picture plane from one end to the other, in counterpoint to the verticals of the fence posts. But it's the color that really made me stop and look. On a drizzly dull day, the row of nearly florescent orange drips came as a real shock. In some ways, this image is a meditation on the nature of rust, starting with the fence itself and the contrast between the last vestiges of cool gray paint clinging to the rough rusty posts. How much time did it take for those lovely drips to form and spread out into such brilliant orange ovals?
