Yeah, I think 10th Planet is original, at least because of the myth behind it (and I don't mean Eddie Bravo).
And even though it's not terribly original, I have to admit that saying that you train at "Rickson Gracie Jiu Jitsu Academy" or any other eponymous academy for that matter, sounds pretty cool.
Ones like "Uncle Joe's Grappling Shack" are pretty funny, too, although I'm not sure that would be a wise business move for a school (maybe OK for a club).
I also like the more formal/scientific sounding ones, like one I saw somewhere called "The Lab." Other ideas would be, "The Institute of Submission Fighting Arts" or "West Coast Ground Combat Academy."
