This project uses cloning to create an expanding circle of balls. It uses the fact that clones get a copy of the cloned sprite's state. Thus, a sprite can set one ore more properties (in this case, its "direction") before creating a clone as a way to set the starting state of the clone. I experimented with two ways to start the balls moving. Using "clone startup", the clone start moving as soon as they are created. The second way is to send a broadcast to start the clones after they have all be created. This results in an expanding circle of balls.
