// get a reference to an element
var stage = document.getElementById('stage');

// create a manager for that element
var mc = new Hammer.Manager(stage);

// create a recognizer
var Rotate = new Hammer.Rotate();

// add the recognizer
mc.add(Rotate);

// subscribe to events
mc.on('rotate', function(e) {
    // do something cool
    var rotation = Math.round(e.rotation);
    stage.style.transform = 'rotate('+rotation+'deg)';
});
