The swirling arms of spiral galaxies may just show these writ large. Then you have spirals within the spirals, and spirals within them as well. Kinda like the way DNA gets packed into coils and supercoils, just less regularly. In some cases I've reconstructed double helical structures, with hints of even higher orders in some open clusters. A lot of the seeming irregularity comes from the angle the structure makes with our line of sight, just as it does with galaxies. As for the other comment sometimes I guess people just wake up on the wrong side of the even horizon....
