Can you see the hidden 3D object or message?
To view a stereogram, start with your eyes about 6 inches (15cm) away from the screen. The image will be out of focus. Keeping the image out of focus, you are focusing sort of beyond the image, slowly lean back until your eyes are 12 inches (30cm) to 18 inches (45cm) away. Hopefully your brain will be tricked into seeing the 3D object or message.
Edit: The image got downsized, this bigger version should make it easier.
