I beleive they start out flat to make sure all the conductors are the same length, and then they "frray" the ends so the ribon will roll and then put them in shrink wrap to keep them round.

I think that's the deal. They're much nicer than the flat cables for airflow... something that's pretty important when you're trying to do what I'm doing... have a very quiet, high-power machine. You need to flow a lot of air at low speeds, and having all those wide obstructions in there sucks for cooling.
