Another example of smooth animations using GSAP and Scroll Trigger. Good for scroll page animations. I cant get this one working correctly in the demo code, you will need to check out the pen ..
Found this awesome animation on codepen, link below, Not sure how re-usable it is, but wow!
Found this awesome animated 404 error page on codepen the other day, crazily awesome animations on this one, just reload the demo page and you can see the animation as it loads in as well.
