Rotoball idea

Today in class Mr. Mark showed to us a video abbot a ball that comes to a person and that person transforms the ball to whatever he liked. My idea is going to be a man that is with a book at the beach and suddenly the balls comes and he turns it first to a kite and he he goes for a up and surf the waves with the kite. Later he transform it to a ball again and then he he jumps and surfs a wave. Later he goes to the beach again and he kicks the ball. I like this because this is what i like to do after school. This would be very hard to do, but it would be original.
