Optical illusions are all over the Web. But only one is mind-bending enough to be called the 2011 Best
The illusion, which was created by Jordan Suchow, a Harvard University graduate student, and Alvarez, an assistant professor in Harvard's psychology department, is called "Silencing awareness of change by background motion."
OK, so the name isn't super-catchy, but the effect is quite amazing. A blog from Scientific American helps to explain what's going on. If you focus on the white dot in the center of the screen, the rotating dots appear to stop changing color. But, in reality, the dots continue to change during the video. "Their spinning motion somehow suppresses the viewer's ability to detect those changes."
You can check out the illusion below. And be sure to check out the rest of the entries over at the contest's official site. Remember what Obi Wan Kenobi told : "Your eyes can deceive you. Don't trust them."
