1. Download four .wav sound files from some site like this (http://www.findsounds.com/types.html). Make an application that plays a different one of these four sounds when the user presses one of the 'a', 's', 'd', or 'f' keys.
2. Make a simple application in which the image of a ball repeatedly moves to some location on-screen that the user has clicked. Each click should play a sound. Each time the ball reaches it's target play a different sound.
3. Write a simulation that simulates balls being fired from the bottom center of the screen at some angle that ranges between 70 and 110 degrees. Some force like Earth's Gravity should act on these balls so that they eventually fall down. Each time the user hits the space bar a new ball is fired.
