The script associated with the 'toss' button was written textually

because of the need to use 'sin' and 'cos' and I couldn't figure out a

way to do that with graphical scripting. The toss button is setting the

x and y of the ball morph. I came up with SetX: as the way to access

ball's x textually by first doing it graphically and then clicking on

the box to show the text for the code. All the other morphs seem to be

OK, the reset button, the sliders and the radio buttons all work as they

should and make the correct sounds.
