Cross view this to see the 3D.
Step 1 - Cross your eyes until you see 4 images instead of 2.
Step 2 - Then relax your view so the images move together and you see only 3 images.
Step 3 - When you see 3 images stop changing your focus and you will see the center image is 3D.
Optional - 4th step - You can also raise your hands to the sides of your eyes to block out the 2 outer images so you only see the center one in 3D!
