Or, if you're as myopic as I, just take off your glasses.

It looks like a zombie Marilyn Monroe, with the weird eyes.

I don't see how this is an illusion. The average pixel intensities form the picture, so of course you can see it from a distance, when your eyes blur the image. This is easy to verify by blurring the image with an image processor. Ten pixel wide Gaussian blur in Gimp produces a faint gray image of Marilyn, with no trace of the pattern.

"An optical illusion is always characterized by visually perceived images that, at least in common sense terms, are deceptive or misleading. Therefore, the information gathered by the eye is processed by the brain to give, on the face of it, a percept that does not tally with a physical measurement of the stimulus source. A conventional assumption is that there are physiological illusions that occur naturally and cognitive illusions that can be demonstrated by specific visual tricks that say something more basic about how human perceptual systems work."
This is an illusion...

What is really cool is that for us, glass wearers, you can see Marilyn with your glasses off, and the image remains for a second after wearing the glasses again, slowly fading away; as if the brain retained the information momentarily, and then reset to the actual information sent by the eyes.

Yourmom - in that case, isn't everything on your computer monitor (or T.V. or in newspapers etc.) an illusion, since it's all composed of tiny pixels? Actually, I suppose that technically they are illusions - but low res images aren't what I think of when I hear "optical illusion."
