Modern Art?

OK, it's not modern art. It is something called a "closed cut valley" in the process of being constructed from asphalt shingles on my roof. There are a couple of tricky bits to this roof - one is called "step flashing," and the the other is this valley. I sat there for twenty minutes contemplating how to do this before starting, and I think I have done it right. I will know when I bring in the shingles from the other side of the valley and see how it all looks. OK, but I actually did take the photo because it looked like an abstract painting, especially with the hammer and hook knife sticking up and casting those unusual shadows on the roof.
