black and white version of colorful migraine auras I get; wavy curves and trianges flashing on and off among brilliant colors
Google images of "Migraine Aura" show varieties of auras; I've had them all, very enjoyable if I close my eyes and just watch the show.
It is troublesome if I concentrate on anything that requires visual acuity because the "aura" creates a large arcuate blind spot
filled with distracting flashing triangles that moves out of my field of vision
