Stereoscopy

Anaglyph

Do you have color filtering 3d stereo glasses? Put them on and choose anaglyph.

Cross eyed

You don't have 3d stereo glasses? Try cross eyed viewing:

• When normally focussing on the screen, you see two slightly different images.
• Disfocus from the screen by looking at the tip of your nose. When you disfocus you see double, so you will see four images.
• Move the images horizontally by changing your focus. Turn the four images into three, by moving the two in the middle towards each other, up to where one exactly covers the other. At this point you are focused for the stereoscopic image. Ignore the images to the left and right. In the middle you should see an image with a perfect 3d illusion.
