Operation is a game that lets you test your hand-eye coordination by removing ailment tokens from a carton patient. The difficult part is that you can't touch the sides of each slot. Since its original release in 1965, there have been a lot of custom versions of this game. There are versions for Star Wars, Iron Man, Toy Story and Sponge Bob. The simple design of the game makes it very versatile and easy to adapt. In this project, I show you how to make your own custom version of the game.
