#4: A New Battleship
Battleship is one of the most memorable games from childhood. Someone decided to make their childhood dreams come true by 3D-printing a new kind of battleship to include in the game. They morphed an ordinary submarine into a U-boat because Battleship doesn’t include that particular kind of ship. Their opponents are in for a big surprise.

This tiny 3D project is actually a huge prank. Any Battleship connoisseur knows that the key to winning the game is to identify your opponents’ ship locations. If an opponent doesn’t know there is a U-boat on the map, how are they supposed to find it and win? Some would say this is cheating, but others might say this is simply an example of innovation. What do you think?
