I am at the forefront of this language. I originally found it on an EqD post by Cereal Velocity, and performed Google-Foo to try to trace down its origins. As it turned out, all there were were the aforementioned post, some deviantART journals and submissions, a forum post about the EqD post and the dA post (yo, dawg...), and a very empty Google Code repository. This upset me greatly enough that I took it upon myself to not only gather all the current information on the language, but complete it in one big document.
Soon enough, it became too big for even a Google Doc to comprehensively define, so I had to move it here. Welcome! This is a place where anyone can contribute their ideas, findings, comments, questions, or example FiM++ programs! Have fun and don't forget to be awesome :3
