Hmmmm, then thing I like about Tween.js is that it doesn't make it's own loop; it's more like Famous Engine's Transitionable where calling
.get triggers it's time calculations, etc, independently of the engine loop. Popmotion, on the other hand, makes it's own loop and would call our API methods on it's own time (instead of us calling it's API on our time as we would with Tween.js).
Question: which method do we prefer? Pros/cons?
