Dino, dragon, and alifont dance to the Morris dance tune "Black Joke" (also called Black Jack). There is also an English country dance to this tune; on the chorus you sing "hey do, diddle-di do." So there. Pressing the C key shuffles who dances to which piece of the music. Interrupting Cow mode: press space or arrow keys. Works with Makey Makey!
I wanted to have a simple oom-pah accompaniment go along with the melody. I thought the best way to keep the oom-pahs and melody synchronized was to make blocks that played each of the oom-pah patterns, and to broadcast messages to the oom-pah blocks whenever the melody starts a new measure. The oom-pah blocks control the dancers through broadcasts. Shuffling the dancers is implemented by rotating through a list. Check out the code!
