Here is an animated web design for the company Paul and Paloma. The website could be scrolled through and animate itself as it went. There is a before animation image and an after animation image so the coder could better understand how to animate the images. In the video you can see how the items would move themselves, and speed would be dependent on how quickly or slowly the user was scrolling.
