Reading about the product on the website, scrolling downward in a smooth motion, then within the same frame, this happened.
As you scroll, you wouldn't be able to scroll pass this frame, instead you watch the little guy walks through the store as you scroll and tooltips popup. This is like front-end candy, gasp. http://estimote.com/ With a bit a inspect element and research, yielded a beautiful GitHub library for this wonderful effect called SUPERSCROLLORAMA forkable and playable. Enjoy.
