Dynamic Luminance-Gradient Effect

Alan Stubbs from University of Maine in USA made this wonderfull optical illusion. This illusion participated in “Best Visual Illusion Of The Year Contest”, and made it to the finals – The Top 10 Finalists to be exact. What you should do is simple, Alan explained: “For the primary effect, one should sit at a comfortable distance and then move forward toward the center of the figure. An interesting change in apparent brightness and to some degree form will result—what may be called a “here comes the sun” effect. By moving back and forth, this apparent change will repeat”. I really liked this effect, so be sure to check for more versions of this image here. I posted few more inside this post…

  4. When you stare at an image for several seconds it gets imprinted on your retina in the back of your eye. You can then see it with your eyes shut and when another image is looked at right away the first and second can unite to give a third image of different combined colors. Similar effects can be seen by moving closer to some images you have stared at which combines the near and far images in the back of your eye or merges different colors to give a new color. It is the same as looking at a bright lite for a short time and anafter image remains for several seconds…
