You're either stressed or stoned.

OK, I can't vouch for the claims made in the text that was emailed to me with these pictures, but it is a really cool optical illusion. You will have to click the little picture to see full size to get the right effect, I believe. They are not animated images!

"The pictures shown below are used to test the level of stress a person can handle. One teacher said, "I felt like they were all moving but slowly like, they were breathing." The slower the pictures move, the better your ability of handling stress. Allegedly criminals that were tested see them spinning around madly; however, senior citizens and kids see them standing still."
