Check out this 3D video of some thrill rides at SeaWorld Orlando theme park. To see this parallel video in 3D, focus on the space between the two videos. Gradually relax your eyes, allowing them to drift slightly out of focus. Your vision should merge the two videos into a single image in the center of your view. Adjust your focus gently until the central merged video appears clear. Still can’t see it? Share with a friend to see if they can. This is the same technique used to see “magic eye” ima
