// This sample script watches your hydra hands and makes clapping sound when they come close together fast // This sample script watches your hydra hands and makes clapping sound when they come close together fast,
// and also watches for the 'shift' key and claps when that key is pressed. Clapping multiple times by pressing
// the shift key again makes the animation and sound match your pace of clapping.
