Stare at the dot for 30 seconds. Then, without moving your eyes, move the mouse over the image.
The image will look like it's in color until you move your eyes.
Click here to leave a comment. I posted a tutorial that shows how to make your own illusion. There's a Photoshop action there that you can download. Of course, you'll need Adobe Photoshop. Also, I made a list of all the versions of this optical illusion that people sent in. If you make your own, add it to the list!
