I would check to make sure this can't trigger migraines or seizures. Maybe it's just me, but also, please double check.
Looking at this it first looked fun: "whoa, that's cool, this fovea thing is really smaller than I imagined"
After a minute or so playing around I closed the window and then I noticed a form of retina persistence that looked eerily similar to an onset of a visual aura, as well as some faint but clear ear ringing, both typical symptoms of the migraines I experience.
I immediately walked away from the computer and although dwindling it's still in effect 10min out.
Basically if it gives you a headache to stare at or just has this sucky attention grabbing feel to it when you look at it its likely to cause seizures. I CBA to dig up the papers on this but there are a bunch if you want to really get into this.
However as the above study iirc doesn't directly state that these patterns cause discomfort and doesn't contain any examples I suggest reading chapter 10 "Photosensitive Epilepsy and Visual Discomfort" of "hierarchies in neurology (1989)" on page 70-71 which proposes this AND contains an example you can look at yourself.
Edit: seems like there isn't enough research to suggest the latter. Apologies
The first part of the comment is very valuable. “I looked at it and it made me feel extremely strange almost immediately“. That is very good to know.
The second bit I’m less sure about. What do they mean by “check to make sure this can't trigger migraines or seizures”? Like what check are they expecting? Literature research? Or experiments? The word “check” makes it sound as if they think this is some easy to do thung, like how you could “double check” the spelling of a word using a dictionary.
