/** 	
	PlayToot03.java

	Fill a MusicShape with random numbers, and add it to two different Players.
	Each Player interprets the same MusicShape differently:
	one with a custom Interpreter that sets the background color of the applet 
	by interpreting MusicShape data as RGB colors,
	the other simply prints MusicShape data to a TextArea.
