FlatWire is flat wire that you mount on the surface of your wall and then paint over.
FlatWire cover any type of wire you’d need including high-voltage electrical, low-voltage lighting, Cat5, 5e & 6 data cables, voice/data lines, coaxial cable, speaker wire, component video, HDMI & DVI. They are currently working on Fiber Optic and outdoor products.
These wires are very flexible allowing you to fold them over on themselves to make and degree turns you want. They then connect to your existing outlets or AV hookups via the FlatWire adapters.
The wires range from 0.1mm to 0.3mm, about the thickness of a cheap business card. You can install it yourself using their spray on adhesive. After you paint over it they would be "virtually" invisible. If you want to get really fancy you can use compound or drywall mud and taper the edges so they would be as undetectable as the joints in your walls.
