Optical Illusion - Black Dots

[Rik]

Weird, isn't it?!

I am shortsighted - if I take off my glasses I can see four if i put my nose close to the screen and possibly one out at each side on the peripheral, but hard to be sure



could be something to do with the way the brain integrates the signals from the macula, and the peripheral, of the retina which work differently [ eg macular is more sensitive to detail; peripheral to low light]

Hidden Images and Stereograms Facebook page has a ton of these. And a few stereograms and a lot of very grade school photos of things that look like female genitalia but are not.

Funny. Looking at the thumbnail image I see red dots.

Very cool Gary. Love this kind of stuff to break a little time while working sites.
