The brown leaf shapes against a green background make this look as if the entire group is flowing—making waves if you focus on the picture as a whole. If you stare at this one long enough you’ll notice a fast and pulsing multicolored vortex. The blue almond-shaped objects look as if they’re all passing over three separate columns. Although this image is comprised of simple purple and green squares outlined in black, it looks like it is bulging out in the center. A collection of black, blue, green and white shapes appears to be five different kaleidoscope-type figures—each swirling toward their centers. The black and white circular lines make this illusion seem as if there are various depths in the image, creating different entryways and tunnels. If you stare at the center of the image, it looks as if the outer rings are rotating in alternating directions—an effect meant to mesmerize the viewer. These bright purple and green star-like shapes appear to be moving, which can be a little nauseating if you stare at it for too long. http://health.yahoo.com/featured/46/8-mind-boggling-optical-illusions/
