Endless.js is a simple jQuery plugin that allows an infinite scroll on any scrollable HTML element.
The idea is to join the top with the bottom or the left with the right. So when you are at the end or the beginning, you can scroll again and you will are done a complete tour.
The Infinite Carousel is a jQuery plugin that allows you to showcase any number of images and videos in a carousel-like fashion. Unlike some other carousels, the Infinite Carousel displays items in a continuous loop no matter how you navigate.
