Ha ha! Uspjela sam, ali samo s kozicom
Evo, nasla sam detaljnije upute na engleskom (za one koji ne kuze kako treba gledati)
1. Place index finger between images.
2. Focus on your index finger.
3. Slowly bring your finger towards your nose, staying focused on your finger, but paying attention to the background images in your peripheral vision. You will notice that instead of two images, there are four images floating about.
4. Continue bringing your finger closer to your nose- you will see the two middle images moving towards each other.
5. When the two middle images are aligned, or are on top of each other, stop moving your finger. You will now see three images in the background. The middle one contains the left/right images overlapped.
6. Slowly remove your finger from your field of vision, while keeping the middle two images aligned.
7. Gradually force your focus out to the combined left/right image in the middle.
8. If you have problems keeping a lock on the middle image, try leaving your finger in the image for a while, but still focusing on the center image. Use your finger to regain left/right fusion.
9. If at first you fail, don't worry. It took me a while. Relax, go away and rest your eyes, and try it again later.
