A system of pulleys that screw to your wall and attach to your light switch so you can turn it on and off from anywhere in the room.
Easily screws to the wall and caps to hide screw heads.
Use fishing line, I use 30lb and it works great. Put one pulley under the switch to be able to turn it off, then just run two lines from the switch through as many pulleys as needed, and then to the pull handles. Keep lines on their own side to avoid tangling
