some months ago I packed 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 press the following key combination to activate the Konami Power!

You can find the Plugin in my Github Repository.

Hope you like it!

P.S.: try it on this page :)
