Rockstar is a language that is unlike any programming language I've seen. Every program you write is... a song. For example, the fizz buzz program goes like this:
Midnight takes your heart and your soul While your heart is as high as your soul Put your heart without your soul into your heart Give back your heart Desire is a lovestruck ladykiller My world is nothing Fire is ice Hate is water Until my world is Desire, Build my world up If Midnight taking my world, Fire is nothing and Midnight taking my world, Hate is nothing Shout "FizzBuzz!" Take it to the top If Midnight taking my world, Fire is nothing Shout "Fizz!" Take it to the top If Midnight taking my world, Hate is nothing Say "Buzz!" Take it to the top Whisper my world
I won't spoil anything by explaining the language's syntax, but there's an interesting presentation on Rockstar by the language's creator, Dylan Beattie. I've set the link to jump to the meaty part of his long presentation.
It appears that the language was created as a goof on the term "rock star programmer", but since the language's announcement, there have actually been compiler implementations created. For all intents and purposes, it's a real programming language.
If we're lucky, we'll see another language in the future called "Ninja" too.
