F.A.Q
    Q: buT cAN iT rUn dOOm?
    A: It can't really "run" anything, its a number.
  
    Q: Is it fast?
    A: Define "fast". If you mean "faster than copying Euclid by hand", then yes, dramatically.

    Q: Why did you make this?
    A: I wanted arbitrary precision arithmetic, but I also wanted to feel something.

I'm wondering how hard would it be to extend it to include the whole game state plus all the ROM into the plane at the same time, and have it compute the next step from that!
