Ok, let's see if I can explain it ANY better! AS you move in close to the picture and you are staring at it, UNFOCUS your eyes so that you're not really seeing that picture as it is, and your eyes almost go into a double vision BUT THE PICTURE YOU ARE LOOKING AT IS NO LONGER *SHARP AND FOCUSED* - forget trying to keep THAT image *in focus* - you are now off somewhere between, not really seeing the picture of black and white specks, but don't blink - move your head back very slowly, and the 3D object will start to appear and get more vivid as it *moves forward*!
Try again?
