Ok, I was lucky in that regard. Now it looks all neat, but the first time I set it up I was really, really sloppy. Fortunately my wife is a lab-hardened scientist, so the conversation went like this:

Me: "Do you mind if I nail these cables to the walls in our living room?"

Her: "Whatever. Just be done by tonight so we can watch something."

This time, I worked with well-hidden cable conduits and it is not that noticeable any more.
