NodeBox for OpenGL

We have released our game development engine. It is available in the new "Download" section on the website. NodeBox for OpenGL is a free, cross-platform library for generating 2D animations with Python programming code. It is built on Pyglet and adopts the drawing API from NodeBox for Mac OS X (http://nodebox.net). It has built-in support for paths, layers, motion tweening, hardware-accelerated image effects, simple physics and interactivity.
