The geometric shapes and the symmetry formed by the intersecting lines make this photo interesting to look at. If you forget for a moment that this is an electrical tower viewed from below and let your eyes be guided by the lines, it almost starts to look like a tunnel to the sky. Of course, a tunnel where you'd be electrocuted or you'd fall off if you didn't watch your step. Come to think of it, I probably shouldn't have been down there to begin with. The things one does for a semi-interesting photo nobody will take a second look at.
