Surely its nice to look at new controlling possibilities, and I would love to see some inventions been made through suggestions.
For me personally its not useable to create a single key for each tori joint, because that would be hard to control with my keyboard.
I would like you to get your idea enabled, since it has something interesting. I think you could handle the tori faster that way.
Could you show us more about your interface with that method ? Which joystick/controller you want to use this with, and how should it look like ?
