Caat by hyperandroid

CAAT is an scene graph director-based animation framework for javascript.

Based in the concept of a timeline, offers a powerful animation environment featuring:

Scenes.
Input abstraction, where touch, mouse, keyboard and accelerometer coexist.
Screen resolution abstraction, where you can make your games up/down scale gracefully.
Multi render technology, making your games render with Canvas, WebGL or CSS transparently.
Clipping masks.
Hierarchycal applied affine transformations, or containers inside containers inside contrainer.
Behaviors, or how to define easily on a timely basis complex mixtures of translations, rotations, scalations.
Easing functions for behaviors, or how to make that path traversal feel more natural.
Easily define (very) complex paths.
Box2D integration.
