For many years I have been a huge fan of a program called Staff Wars 2 by a group called TheMusicInteractive. It even made it into my High-Tech Low Budget Music Technology Special last year. This free program for Windows and Mac is awesome for young instrumentalists to help them learn fingerings and practice playing notes on the staff. Basically, a note floats across the screen toward your "shield" and you have to play the correct note on your instrument before it hits it and you lose a life. It uses the microphone attached to your laptop or plugged into your desktop to do it.
