Is this what you see here the ghost of Houdini? Well no, of course not, but you just might think it is after you’ve viewed this awesome original illusion created by Bob King. To explain how it works: open the picture below, then, with your eyes about 12 inches away, stare at the white circle nearest the middle of the image for 60 seconds. Now close your eyes and tip your head back a bit, keeping your eyes closed for about 20 seconds. Wait to see if Houdini’s image slowly appears! You can do this also by starring at white surface. As some of you old timers here noticed, it’s really similar to Original Jesus illusion, but there were also light bulb and Batman illusions, located in afterimage category. Oh, almost forgot about USA flag illusion!
