Buzztec Flute

I dusted off a set of PS2 Buzz controllers and playing around with some ideas to use them in games. 

This utility lets you use one of the controllers like a 4-hole ocarina. It's not perfect but a lot of fun to play. 

To play, place your left index and middle fingers over the top 2 buttons and your right index and middle finger over the bottom 2 buttons. Then use your chin (or any other convenient body-part)  to press the big red buzzer to simulate blowing into the mouthpiece.
