I was just thinking my wife wouldn't find that appealing.
The idea of the led lit cables would be pretty cool. Get an extra long cable and spell a message, kind of a neon sign effect. Which would be good for stereo listening but to distracting for home theater use. People already complain about bright lights on their equipment.
I get a kick out of the other picture in the article. They're using in walls for the front mains for that nice clean look, then do that with the cables from the playstation!
