Came across this in my many travels across the internets:

Looks like an interesting solution.

Does anyone have any experience with this type of wiring? How do you handle curves and turns?

No direct experience, but I would say try not to crease it too much in/around corners since the metal could break. I've read many reports that there is essentially no difference between this wire and comparable gauge "normal" wire. I don't think it is designed to turn right or left, just straight shots since it is so wide. I'd say run it along the bottom til it is supposed to go up the wall, and just have a straight shot up the wall, which can be made invisible if you really want to paint or even mud it in.
