Hi, Could this be true?The pictures attached are used to test the level ofstress a person can handle. One teacher said, "I felt like they were allmoving...but slowly. Kind of like, they were breathing."The slower the pictures move, the better your ability of handling stress.Alleged criminals that were tested see them spinning around madly; however,senior citizens and kids see them standing still.FYI ... None of these images are animated - they are perfectly static! enjoy.........
