1. This image is just to warm-up with. Spot a problem?
2. Follow the instructions engraved on the image.
3. Are the purple lines straight or bent?
4. What do you see? Look again . . .
5. Do you see gray squares in between the lines? Now where did they come from?
6. Take a look at the following picture. It is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or look at the black center of each circle and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it…. Weird
