How to see the artificial 3D-effect:

Sit in front of your screen at about 30-50cm (10" - 20").
just try to look relaxed at the middle of the image and begin to squint a little.
the left and right image begin to overlap and form a 3D image in the middle between the two images.
You will notice it if you are right when you see the 3D-Effect.

The first picture in the animation will last a little bit longer to give your eyes and your brain the chance to accommodate.

have fun and please share your opinion and your experience in my guestbook.
