South Pole After Image Optical Illusion

The nature of this optical illusion is to paint a grey scale image using only your eyes.

Below is Lieutenant John Bortniak out for a stroll at the South Pole.

Focus on his nose in the center for 30-45 seconds then move your mouse over and the image it will then swap to the grey scale image, but you will see the original image in all it's glory.

Stare at the image below. It will show the negative image for 10 seconds and the gray scale image for 1 second. The longer you look at it the more pronounced the effect.
