We can subtly alter the effect by changing the easing equation to easeInQuart for the top property only, causing the element to follow a curved path rather than a straight one. Remember, however, that using any easing other than swing or linear requires a plugin, such as the effects core of jQuery UI (

.each((i, element) => {
      left: 0,
      top: 25 * i
      duration: 'slow',
      specialEasing: {
        top: 'easeInQuart'
