parallax.js
parallax.js reacts to the orientation of your smart device, offsetting layers depending on their depth within a scene… Oh, you don’t have a smart device? No worries, if no gyroscope or motion detection hardware is available, parallax.js uses the position of your cursor instead. Radical.
It’s simply awesome .js. This project is a collaboration between Matthew Wagerfield & Claudio Guglieri.
