Original Message "The pics attached are used to test the level of stress
a person can handle. The slower the pictures move, the
better your ability of handling stress. Alleged criminals
see them spinning around madly while seniors and kids see
them still.
If you still think that there's a trick here, you may
wish to print it (even black and white) and by then you're
sure that it's a still picture...
Look at it again and check your level of stress..."

While stress may be a small factor in how fast the images
appear to move, this is just a basic optical illusion not a
real stress test. But it's still neat.
