Unintentional art

I'd kind of like to have this abstract on my wall. In fact, it could actually be the wall. I found this piece of serendipidous art not long ago down by the river at a construction site. It's a large metal fence/wall panel that had been probably used flat at one time, since it bears traces of rust and paint that form abstract patterns. I actually have a whole series of these photos, and can't make up my mind which one I like best!
