morph to this style:

// remember
var foo = $('foo'), originalStyle = foo.getStyles();
// apply CSS class
foo.morph('here');
// ... skipped
// morph to original style
foo.morph(originalStyle, {
  afterFinish: function(effect) {
    // remove class name after finish
    effect.element.removeClassName('here');
  }
});
