The well-loved and possibly most-remembered “secret” code of all time, the Konami code, is waning in significance. Unless you’re a frequent Gradius and Contra player (though I can’t be the only one), you probably find few occasions on which to use it. Fortunately, there are a few games, and by games I mean websites, out right now which will take the code. Unfortunately, it no longer makes ESPN pony time.
All you have to do is go here… and enter the code.
Via Metafilter, where I also found this amazing illustration of the code, Da Vinci style.
