Info from Licensor: "The video is a compilation of three optical illusions entirely created by me. First, I drew all three animations. Each animation consists of 6 pictures. Then I created a computer program that uses them to create a single image. With the help of a properly printed sheet, you can watch the entire animation. Even though we only see about 16 percent of the entire picture at any given time, our minds are able to complete the rest."
