Vanilla JS on mousemove. Make sure to add 'data-offset' attribute and specified class to element.

mouseMove.js

const mouseMoveEls = Array.from(document.getElementsByClassName('transform__mm'));
  document.addEventListener( 'mousemove', (e) => {
    const width = window.outerWidth;
    const height = window.outerHeight;
    const offsetX = 0.5 - e.pageX / width;
    const offsetY = 0.5 - e.pageY / height;

    mouseMoveEls.forEach((el, i) => {
      const dataOffset = parseInt(el.getAttribute('data-offset'));
      const translate = `translate3d(${Math.round(offsetX * dataOffset)}px, ${Math.round(offsetY * dataOffset)}px, 0px)`;
      el.style.webkitTransform = translate;
      el.style.MozTransform = translate;
      el.style.msTransform = translate;
      el.style.OTransform = translate;
      el.style.transform = translate;
    });
  });
