I can't stop watching this video. It is a fantastic animation of a walking cat, made to look like a hologram. The animation was made by David OReilly. Its 3D effect is created using anamorphosis warping and an assumed viewing angle. The effect really pops with the addition of turning the device. As the phone is turned, the gyroscope senses the movement and adjusts the animation appropriately to change the cat's direction. Amazing!
