Christ Portrait - Illusion

This portrait is an illusion! Just stare at the center of the portrait for 15 seconds without looking away. Count 1000-1, 1000-2,... etc. After this look away and stare at one blank spot (say, on the wall) for another 10 seconds ... watch what appears! The portrait is a standard 8x10 and currently comes with a frame (whatever's available). It makes a great conversation piece.
