I have seen a few websites which have used CSS3 animations on their pages. When you scroll down a small animation happens (either a small shake or grow effect). This animation then stops so you can read the page.
I have found this script, http://lab.hakim.se/scroll-effects/, which looks to what I need.
I tried to adjust this but I have not had much luck. I am not entirely sure if this would work without the scroll box and only the scroll on the browser.
If anybody had any experience with this I would be very interested to know.
