If you want to see the 3 dimenional effekt , u have to look at this picture with a special technique.. Its called "crossview" u have to cross your eyes... the left eye looks at the right pic , the right eye looks at the left pic
just spuint....cross ur eyes ...not so far that u see 4 pictures (made out of 2)...just so far that u see 3 pictures...the 3rd pic in the middle has a 3 d effect
it needs some excersice but its fascinating
the picture shows some sandsculptures made in germany during a sandsculpture exibithion
