FlatWire
FlatWire eliminates unsightly bulges and wallwarts by replacing power and speaker cables with ribbons. They can’t do 120 AC yet, but it sounds good for those low wattage DC light installations, or speaker wire. You glue ‘em right to the surface of the wall, then spackle, sand, and paint over them. The result is invisible when properly installed.
It’s a great idea, but I think the key phrase there is “when properly installed”. You might want to try a test run in the basement rec room before turning your attention to the master suite.
