Most forms of work possess a certain level of artistry. Wiring and plumbing are no exceptions. Like most of us, I have a fear of my home catching fire or of the pipes bursting. I don’t think about it all that often until I come face to face with evidence of a really bad job. Or, for that matter, a really good job. Regardless, I am fascinated by schematics, and especially so with those that either represent a system that is highly functioning or one that is on the verge of failure.
