In addition, I think it's relevant to add these images to this discussion.
The first image is one of a piece of paper with a 'star' pattern made from black tape.
A video camera is focused on this paper and its output is fed into a Sony crt.
The second and third images are of a cylinder magnet placed on the face of the crt, and each results in 'twisting' the image while displaying the magnets field at the same time.
The forth image is one that I 'borrowed' from the Wolfram math site showing the derivitive of a 2D Gaussian field. Notice how the graphic matches the crt image perfectly.

Note that the magnet is oriented 90 degrees different than the images in my previous post. Instead of the field being parallel to the glass, it's perpendicular.
These images were made by my good friend and fellow collaborator, John Shearer: http://www.nanomagnetics.us/jshearer.htm

Here are a couple of images of a sphere and cylinder magnets on a 'good' Sony Trinitron:

I started to post this before, but the website hiccuped and I lost the text. Needless to say, wife and kids prevented me from getting back until now. Ok, those pics are way kewl and I see something weird. The first pic, quad I think, shows a definite 4 node pattern. I agree, I think you have a good captured image of the Bloch wall. I also think you've captured something else. Images of null zones right in the middle of the poles as well. It looks to my untrained eye that the fields are toroids with the wall between them and also null areas in the center of each torus. The southdown and northdown pics also seem to confirm this and show a rotation perpendicular to the field alignments but instead of the torus, the field lines look more like envelopes. Yet again, the sphere and cylinders are different again, showing what I would have expected, a singular envelope of field lines with no poler or Bloch wall null zones. I wonder, are all of your samples using Neos or are some of these other types of magnets and what are the alignments of the sphere and cylinders pics?

ps. Have you tried a hard drive magnet. They are double aligned through the face.

pinestone, thanks for the pictures.

I like the second picture (quad.jpg) it shows the bloch wall area not being dead.

I particularly like the 5-th and the 6-th pictures (southdown.jpg and northdown.jpg)
I have no words, the pictures themselves are sugestive.
I will just use out of context your saying,

This is where north twists into south ...

Yes, the crt displays are mind boggling. It's like having a particle accelerator.

Even though I understand the technology behind the cathode ray tube, these magnetic patterns are still fascinating and open to interpretation. For example, why are there multiple sets of bands? Are they representing actual concentrations of flux?
If you know anything about the composition of a color crt you realize the three colors- ie red, blue and green are at equal phase from each other. The above images seem to suggest that each concentrated band of flux is 'moving' in a different reference frame (time).
Looking at my images (above), red is north, blue is south and green represents 'neutral' or the region where these two opposites meet (Bloch wall).
I believe these images represent a 'slice' of the field. Like cutting an onion in half. There's no doubt in my mind that the field is composed of opposites. If we discard common belief and imagine the bands of flux are 'traveling' in opposite direction, this would still satisfy any magnetostatic equation and equal zero at rest.
