Nature's mysteries

Curious icicles hanging from my roof this evening:


The round hook-shape would seem to be the effect of water freezing to the side of the raingutter before descending to form the straight icicle form. What surprised me, though, is the fact that the icicles now point away from the apartment. Compare that to this photo:


Here, the weight of the sliding snow has caused the icicles to curl inward, toward the building. But the icicles on my apartment have somehow managed to rotate outward. I have no idea what can cause them to move that way.
