on my phone at typical distance and 90 scale i only see about an asprin tablet size area spinning. but at 180 scale i see almost everything spinning at same distance.
i think peripheral vision is quite sensitive to movement/contrast changes, but the moving shapes have to be large enough to trigger those receptors?
You can see everything in your field of vision, but the area DIRECTLY in the centre has the highest level of detail. This image has high frequency animated details that are not cognisized equally by your entire FOV. The animated bit right in the middle at any given time is where your brain processes the most detail and also where you are looking.
Hi, I don't know what this is supposed to do, but I get pretty bad migraines and loading the page made me feel extremely strange almost immediately so I closed it.
I would check to make sure this can't trigger migraines or seizures. Maybe it's just me, but also, please double check.
No, there should be a shader (think video) rendered showing a bunch of tiny spinning things. Something went wrong when you tried to load the page. It's an optical illusion where only things close to the centre of your vision look like they are spinning and everything else looks still.
TL;DR it helps you identify the true diameter of your visual focus, which is said to shrink with old age (mine shrinks more in terms of _time_ dimension but that's a different issue!)
For best results, use it _fullscreen_, change the #define `90` values to a higher value if you're on a high dpi screen.
Stare at a few places on the screen and you'll get the effect of appearing to rotate only where you stare.
Hah, so my comment here spawned a post: https://news.ycombinator.com/item?id=45904434
Yup :)
ok, i dont get it.

not sure what to conclude from this.
Does anyone know how the hell this works

Oh cool so it’s about the frequency?

Its supposed to show you how big of a radius your eye can focus on at a time, as we age the radius shrinks.
Edit: seems like there isn't enough research to suggest the latter. Apologies
I don't know why you got downvoted. This seems like a very useful contribution.
I don't get it, all I see is:
"Bad request"
am I missing the joke?

Okay, thanks.
This is a truly incredible demo.
What’s the correct scale for 210dpi?
180 worked pretty well on my Framework 16.
Ditto on my MacBook Air

It's pretty neat.
Amazing - but iPhone screen is too small. Works on my iPad.
Just zoom in a bit
Worked on my iPhone
