Stress Test

How stressed are you?

The following three images are all completely static. There is no trick involved. If you stare directly at any part of each of them, you will see they are not moving.

I can't explain exactly how, but if the image is moving it is because of how your eye is seeing it, and your brain is interpreting it.

Ideally, the pictures should not appear to be moving at all. If they are moving slowly you would be experiencing normal levels of stress. Young children and senior citizens should see them standing still. If you see them moving rapidly you may well be under considerable stress and I think it's time for you to take a holiday...
