Unless I didn't wait long enough for it to turn into a screamer, it's a static image with no sound. The post that went with it is probably right about people with art knowledge being able to explain how the picture can draw you in. That's not me, but I'll post some thoughts anyway.

I imagine the light color of the eyes are part of it. My niece has crystal blue eyes and they really draw your attention. The eyes are also in the center of the image, a pretty natural place to look and focus. As for the other bits, that staring at it is hard and you start to see changes, I think they're basically optical illusions. I suspect things like persistence of vision or after-images caused by the staring cause the changes. Also, I've heard from a lot of courses over the years that humans are pretty good at seeing patterns and things that don't really exist. (I don't think it would be too hard to search out info on this if you're interested.) So I think the changes in the image are basically imaginary. And staring at just about *anything* for a long time eventually gets hard, doesn't it?
As for people killing themselves after staring at the image, I find that hard to believe. If they were already unstable or leaning towards suicide, then *maybe* this could push them over the edge if they got overwhelming feelings of sadness or something.
P.S. -- Great logic there, Sabaku Ika.
