How to see these photos correctly? You have to put your eyes crossed and wait until you see three photos. First you see four photos! Then you must move your eyes until you see three photos. At this moment those photos are unfocus but you must wait, then your eyes are getting use to it. This may be hard at first time!
This is an interesting project to make a poor old grandma go cross eyed Antti. The picture is compitent and useful for 3D but not one of my favourites of yours )
