How the eye works - Plus a lesson in psychology.
how the eye works

This is one of the few pictures on cool optical illusions that is NOT an optical illusion. This is just a diagram of the eye, and how the eye relays the images to the brain to form pictures. Notice that the picture of the flower actually gets formed on the retina upside down! Your brain actually flips the image right side up.

Time to learn something:
Scientists actually did a study on some people by giving them mirrored glasses, which they were required to wear contstantly for days. These glasses had the effect of making everything they saw turn upside down. Although very awkward at first, after a week or so their brains actually started flipping the images right side up, and it was just like before! Then when they took off their special glasses, everything was upside down for a while as their brain adjusted!

Learn something else - a short lesson of group dynamics, how psychologists used an optical illusion to discover something really interesting!
Did you know that if you project a spot of white light on a wall in a dark room, and look at it for a few minutes, it will appear to move? Even though it does not actually move? Psychologists used this in a famous experiment where they would take a group of people and show them the spot of light. Then they would ask how far the light moved. The interesting thing is that the psychologists actually had only one real participant in the group, and the rest were working for the psychologist.

In group A, The "workers" would all report a much larger distance than they had actually seen: for example 14 inches. Then Participant A would answer. In group B, they would have the participant verbally give the answer first, so as not to be swayed by the group. As you might expect, the participants in group A reported a much larger movement than those in group B, even though they had seen the same thing!

Furthermore, the particpants in group A didn't only report a larger number to sound better to the group, they truly BELEIVED that they saw the line move much farther.

So just remember, if you are trying to persuade someone to believe something, a technique you can use is to have others who share your opinion talk about it first, so that the person sees that they are in the minority. They just might start to remember things differently!

Best of the Best (our newest original optical illusions)
Diamonds appear to be the same shade. But they're not!

Same Shade Diamonds

Wow! It will look like the diamonds on the top are much darker than the diamonds on the bottom.

Perfect and printable! This is a very strong optical illusion, and is even noticeable in the small image to the left. Doesn't it look like the top row is considerably darker than each successive row?

moving red spiral

Moving Red Spiral
Sometimes, while I'm just playing around in Photoshop, something appears, as if by magic. This illusion was one of those that just jumps off the page.

It's a large red spiral on a purple background that appears to jump and move. Works better for some people than others, but if you like the moving illusions, you'll love it! Although this small image might move a bit as you read these words, the larger versions are even better!

It moves! You must zoom in to get the full illusion. You'll see the rings rotate, even though they are not moving at all.

We've created several sizes so you can use as your desktop background.
