The following video was created by Guy Wallis and David Lloyd from the University of Queensland in Australia. It was selected as a finalist for the 2013 Best Illusion of the Year contest hosted by the Neural Correlate Society. The video presents an ambiguous pair of cubes that can be interpreted in multiple ways. As the cubes rotate around, your mind thinks it knows what is going on. Then they begin to rotate again and an entirely new interpretation is presented.
