If you enjoy the classic video game Ninja Gaiden and Papercraft you will get a real kick out of the downloadable paper Gaiden. As you can see from the above image, the art style is almost a perfect recreation of the NES version of the game. You can see more screenshots and download the pattern for free over at Gamer Limit. You might not be turned into a ninja by completing this, but you will develop a blackbelt in paper folding by the time you are done.
