I've been trying to model a similar effect, but on a much larger scale replacing all the green rods with a lightning effect. Here's a picture of my first attempt, which I've gotten to look a little better with practice.
I wound up using steel wool, which you can get real cheap at most hardware stores. Just carefully pull out individual strings, it's real thin so it will cut you like a razor blade if you're not careful, and twist them to shape.
