This optical illusion was first created in 1861. Look at the two thick vertical lines. Do they look straight or curved to you? Hold a ruler up to the screen and you will see that they are indeed straight.
Would you believe that the colors of squares A and B are the same? They are!
Use your fingers or a piece of paper with holes cut through it to block out the rest of the picture and you will see that they are.
When you move your eyes in a circular motion around this image, you will see what appears to be spokes moving around with your eyes.
Though I admit I see it better when I scroll the page up and down :)
Mint Chip Ice cream, Krispy Kreme donuts, homemade pizza, pralines, Chinese chicken salad...mmmmm!
