A little trivia about Pac-Man
When you play the game, it might seem as if the four ghosts are actively chasing you. That's not exactly true. Iwatani intentionally avoided programming them with that purpose, since that would have resulted in Pac-Man zipping around the screen with four ghosts always right behind him.
Instead, it's only Blinky, the red ghost, who doggedly pursues you throughout the game. Pinky, the pink ghost (naturally), simply wants to position itself at a point that's 32 pixels in front of Pac-Man's mouth. The blue ghost, Inky, is seeking to position itself at a similar fixed spot. And Clyde, the orange ghost, moves completely at random.
