Go here. Stare at the black dot til the picture of the castle appears, if you don't blink or move your eyes, the picture of the castle will appear to be a color image. It is not a color image, it's black & white. If you blink, or move your eyes the teensiest amount, it will revert to b&w.

Kooky.

that is pretty cool

I found that I could make the image appear in the correct color after staring at the dot while the inverted colors were displayed. I also found that I could make the black and white image return by shifting my focus point. But I also found that I could return my focus to the black dot and see it in the correct color again. the moves have to be pretty quick and direct, not moving over the screen much. It's like your retina becomes... "stretched" in a particular color direction and takes a little while to return to it's regular state. While it's "stretched" that image lasts for a few seconds, but the colors only map to the image while the tonal values also match, ie, aligned with the focus on the dot.

Really, you can pick any point on the image and do the same thing, there's nothing super special about the dot except it helps you anchor your focus on one tight spot, rather than fuzzing up the image on your retina.

Remember those Magic Eye pictures? They looked like a bunch on spattery gobbley-gook, until you learned to cross your eyes in a particular way and then an image seemed to jump out of the page. I learned to do that fairly well, and I've tried it with the image above and I'm able to move the separate images together in my field of view to turn her brown eyes blue, to borrow a phrase. She looks like a scary zombie when I do. A pretty zombie to be sure, but with scary looking eyes.

I did that, too.

It's remarkable how much of a difference the eye color makes. I could swear that the face is a different shape and the mouth is open a slightly different amount, but they aren't.

T-Shirt Face sees you, do you see T-Shirt Face?

Nope. Look again.

The 180-degree circle...

really cute babies.... but I'm not getting the optical illusion about a 180 degree circle.

Same image - 180 degrees apart. Full circle in half the time?

wobble wabble wobble....
