We (Hampton Creative) had the opportunity to re-design the website for American Telephone last year. I developed a lot of custom animations that travel down the page with you. However, you should check it out on a desktop. We opted to cut out most of the flashy stuff for the mobile experience.
When I started at Hampton Creative, most of what I did was simply executing a designers vision. Most of those visions were very static. This was the first site where I got to influence the design process on the front end by pitching my ideas for the site. The design itself wasn't mine, but some of the concepts for the animation were. And of course, I did do all of the development.
