Click/tap and drag the overlay to animate the cat. Click/tap the play button to make it move automatically. Click/tap the "Next" button to switch between 4, 8 and 16 animation frames.
This project demonstrates that the more animation frames you use, the less of the image will be visible. In the animation with 4 frames, the animation isn't smooth, but you see 1/4 of the image. In the animation with 16 frames, the animation is smooth, but you only see 1/16 of the image.
