This may not appeal to everyone, but what I did was simply cover most of the wires with 4" corrugated PVC pipe cut in half, box out the dangerous stuff, then paint all the exposed joists with flat latex paint. The color was charcoal. I primed the ducting with automotive primer in about the same color.
Then, with tract lighting aimed both up and down, the affect was very much like what you see in restaurants. It was very easy to do.
