Driving in rural VT yesterday I noticed spiral icicles hanging from a few power lines along the road. One section had about 5 of them almost touching the ground (~20 ft.). Any idea what would cause this? More details inside.

They're hanging from power lines, which will oscillate in the wind. That could cause it. I'll bet if you knew the freezing rate, wind speed and direction, and powerline length and thickness you could graph the size of the coils of ice as a periodic function, or at least get pretty close.
