PaulTon: This is a daft idea, when i tried, the ball kept landing with the letters away from the camera. I looked at reverse camera view but the ball i see says TP on it, can't be mine.
Funny I had the same problem, so now if I cant see the initials when I get to the ball, I write them on the other side.
Only down side is there are very few parts of my screen I can read now. I am yet to figure out why because I only write on the ball.
