Sprite3D.js makes it easy to manipulate HTML elements through CSS 3D transforms using a ActionScript-like syntax and hierarchy, and a bunch of chainable accessor methods.
A Sprite3D object is a simple wrapper around a DOM element providing helper functions and properties. You can conveniently use CSS styling to determine the aspect of you element, and CSS transitions to animate your stuff.
In many cases, 3D transforms are GPU-accelerated, giving you an incredible performance boost.
