The final animation is sort of an encore of 2 previous popular animations. There was pacman and there was the gun. So I combined them. Pacman eating the bullets from the gun.
Below are links to the images found in this video so you can print them out and try it yourself. You'll have to print the template onto a transparency. If you have an ink jet printer you have to use a special transparency made specifically for ink jet printers. When you print the images and the template make sure to print them all at the same size if any of the sizes change the effect will not work.
