Even beer kegs on the bag of a truck can make for an interesting photograph, if you try hard enough. There is a quote from Günter Grass' novel The Tin Drum that I like very much, and I think captures the feeling of a kind of nervous energy that I was trying to put words to the other day. "...At this moment I undertsood the fatal lure of the thirty-foot springboard; little grey kittens began to wriggle in my knee joints, hedgehogs mated under the soles of my feet, swallows took wing in my armpits, and at my feet I saw not only Europe but the whole world." I really like that. If you've not read the book, give it a go.
