Project Notes

Watch the balls bounce on the piano keys to make strange music.

Drag the black paddles to a new position to change the timing of the bouncing balls.

Balls can be turned on or off by clicking on them. You can do this while the machine is playing - which is a little tricky or by turning the machine off and then clicking on them. Slowing the balls down or trapping them close to the keys makes it easier to turn the balls on or off.

Drag the two ball alignment icons along the right side of the display to align the balls to a new position.

You can turn the machine off and play each key manually by clicking on it if you like.

Lastly, you can change the speed of the balls using the slider at the top left.
