Some months ago I implemented the Konami Code into a small jQuery-Plugin so you can give your users the power of the Konami Code. For those who don’t know what the Konami Code is:
The Konami Code, known in Japan as the Konami Command, is a cheat code that appears in many Konami video games, although the code also appears in some non-Konami games.
You have to type/press as fast as you can!
You can find the plugin in my Laboratory: http://lab.codecookie.net/konami-code.
