They look really nice, but I have no idea what any of those symbols mean...
They are related to the Neon genesis series, and possibly the extended series etc someone else who knows / have watched more than me.
Eva 01 is the Eva unit 01, NERV is the name of the agency operating Eva units, I can't recognize / can't remember what the symbols on the black key is. I saw the Eva racing symbols somewhere, possibly without the "Eva racing" english line.
