I had a slightly different reaction: I was very distracted by the visual artifacts (brain processing, not the actual image), especially around the edge of the circle.

I was as well - everytime I see one of these they also pause too briefly at the change over from inhale/exhale and back.

It's disconcerting because its not how I naturally breathe.

maybe this one works better?

Indeed. I kept wondering if the circle was actually getting lighter as it got smaller or if that was just how I was perceiving it due to the afterimage and whatnot.

It does change color ... right?

This is a very HN exchange

task: stare at circle

HN, staring at the circle: they could use CSS for this instead of JS

Yes! In my periphery it looked like a polygon but when I focused on the edges it seemed like a properly antialiased circle.

Yeah I saw the same. A rounded-corner polygon.

Interesting, I saw the same!
