What I find interesting is that the auras that I get as a precursor to my migraines don't look far off from those images.

If you were to take a C shaped slice and overlay it onto video and then animated the color you would pretty much have it.

It would be interesting to see if they were connected somehow...

Sounds like you are describing "scintillating scotoma", if you wanted a name for that visual distortion.

That's interesting, it also resembles the patterns I see on LSD or 2C-B

Yes, same here!

I get the vivid flickering lights occasionally (in a C shaped slice as you describe), but luckily don't get the headaches.
