This week’s illusion, by vision scientist Alan Stubbs from the University of Maine, competed as a top ten finalist in the 2006 Best Illusion of the Year Contest. To experience the illusion, sit at normal reading distance in front of your computer screen and then lean forward toward the center of the image. An exploding supernova of brightness will ensue. Move your head back and forth in front of your monitor to experience shrinking and expanding brightness.
