It's worth pointing out that PocketMonkey (http://www.pocket-monkey.com) doesn't support Go just yet (I'm only one man). It does have Gomoku, which is a much simpler game, similar to Pente.
As for martial arts, I spent much of my mispent youth learning them. I found Judo to be too...corse...for my tastes. I think you might be happier with a form of Karate (I'd suggest Kenpo), or Aikido.
Jock: Interesting. I was thinking more along the lines of using an already existing vector and altering it to my advantage. -- RossOlson
