Do not trust your eyes ...
One of the first things you learn as a forensic scientist is never to trust your eyes too much. Why? Because they can be fooled and misled easily. It's always much better to take measurements to confirm your visual observations. You don't believe me? See for yourself.
Are those lines straight and parallel or not?
What I find fascinating about this picture is that the brain has no difficulties to identify the lines as parallels as long as the pattern is regular as on top and bottom. But when it gets sort of irregular in the middle, the it is fooled.
Circles or spirals?
And now have a good look at the last one:
Do you see them moving?
I assure you after experiences like these you begin to see some eyewitnesses' statements in quite a different light. Although made in good faith they need not necessarily be true. As the circles are not revolving of course although you see them do it.
