I don’t get so much of a rainbow effect, and the shimmering edges of mine are more hairy than blobby if that makes sense. But yeah, pretty good representation.
Note to non-migraine-enjoyers: the grey blob in the video isn’t grey, it’s just an area you can’t see in. Your brain tries to fill it in the best it can, as it does with any eye damage, so you might see a blank region on a page when there’s actually text there, for example. This means the shimmery bit isn’t at the edge of a grey blob, but a strange nothing-zone of fuzziness where things that “enter” the zone may or may not vanish, and which feels distorted and wrong, like a fun-house mirror and a kaleidoscope at once. If they get big enough they kinda go blank, but still aren’t really grey—I’m not sure what color you’d call them.
(At least for me—maybe some people really see a grey splotch?)
