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…
