You could just see this another wall with ivy growing on it. Or you could see it as a deeply symbolic photo representing the conflict of "man vs. Nature," and our attempt to impose structure and pattern on a universe that is as random as the ivy's vine creeping across a red brick wall.
What was I thinking when I took the photo? Frankly, I was probably thinking that I liked the yellow tint that seems to edge all of the leaves. More likely, I wasn't thinking at all. . . .
