Our friend Pacman is experiencing something disturbing here. He is discovering infinity!
This is something I've experienced too. There were three mirrors making a triangle, with the reflecting sides inside the triangle. When you are inside, you see your own image reflecting forever...
Well, this scene was built just like that: three mirrors in a triangle, and Pacman in the middle. Yes, there's only one real Pacman in the scene (the biggest on the image), all the others are just reflections patiently calculated by POV-Ray.
