AFTER  IMAGES     After images are caused by staring at something for a long time. Your optic nerves are continually sending a messages to your brain. It is in your brain that the information is translated allowing you to see.     However, if you stare at an image without blinking for a while, the same message is sent thousands of times per second.  If you were to close your eyes, you would see the image, but in different colors.  Close your eyes now and you will see your monitor screen, but with lighter colors.     Here is a new twist on that scientific fact.   1.) Click on the skull and stare at the center of the optical illusion for 30 seconds.   2.) DO NOT BLINK  3.) At the end of 30 seconds, continue to not blink and stare at the back of your hand.  4.) Enjoy until the after image disppears. No mystery, just the way our optic nerves work. TO MESS WITH YOUR MIND CLICK ON THE SKULL
