Want to See a Migraine?

Warning: these visual illusions won’t be comfortable. They may, in fact, have the potential to cause seizures if you’re so prone.

The page says simply, “This page may feel you sick.” (It’s Japanese.) It didn’t. In several places, I didn’t even register the anomalous motion that was supposed to occur. Then it hit me. I could see it, but I was discounting it. The scintillating effect the author talks about is what I see when I have a migraine, only I’m looking at a normal computer screen (or the sidewalk, or the wall, or the inside of my eyelids). I’d just forgotten that most people don’t see that at least once a week.

Welcome to my world.
