A very cool illusion!

Thats awesome! At first I was like oh they just change it to a color picture...thats dumb but then I did it with out the staring and released that the new picture is in B & W
 
Nice! Just be sure to avoid moving your eyes once you move the mouse back onto it - any movement destroys the illusion.
 
It's due to eye fatigue or something like that. I like the example w/ the US flag, saw it in a psych class once... *wonders if someone else will/can find it online*

Even better if you can block out all ambient light...

When you stare at something long enough, your eye "memorizes" it, so to speak, so it retains the image on your retina for a certain period of time.

Not exactly like, but kind of like if you press your finger on a darker part of your arm and then lift it up, the area where you pressed is lighter for a few moments.

Anyway, how this works is they've essentially "subtracted out" some of the color information from the file, leaving a grayscale version and a partial color version. When you stare at the color version for awhile, those colors are "pressed" into your retinas so that when you subsequently look at the grayscale version, it looks to be color since the color image is still on your retina and overlays the grayscale image to make it color.

Yep, it's the image staying on your retina type-thing. It's like those images where you stare at a pattern for 30 seconds and then look at a blank wall, and you see it 'projected' onto there – in this instance, the image on your retina combines with the mono image you're looking at on screen and fools your eyes into thinking you're lookin at a colour image.

None the less, very cool indeed. :cool:
 
Basically your eye holds the color, and you see the inverse for a moment.

This is what you'll see...I took the first image, inverted it in Photoshop, and overlayed it on the second image.

That's cool. But I have one that is personally my favorite, open the link with iTunes or something in the back and once you stare at the gif file for a while, close the window with command+w to really get the most out of the effect.

Have some fun and combine theses two. Stare at the jesus for a long time, and then star at the spinning Yo thing. Then stare a blank page in your browser. Exploding Jesus! :eek:
 
I love optical illusions. This one is definately one of the best ive seen

Cool.

This reminds me of an exercise that we went through in flight school. One of my favorite illusions.

Steps:

1. Find yourself a very small red (must be red) penlight.

2. Locate a room that is absolutely black (no outside light).

3. Set up the red penlight at the other side of the room. Preferably in the top corner of the room.

4. Stare at the penlight. Do not move your eyes.

If you are successful, after around 30 seconds, something really interesting happens. It is very important that you do not move your eyes off of the penlight. You must keep focused.

Good luck. :D
