[open source] EffectNodes for cocos2dx

hi, i made some 2d special effect demos and gathered them in the EffectNodes-for-cc2dx project.
here is the page:
http://git.oschina.net/wantnon2/EffectNodes-for-Cocos2dx
or https://github.com/wantnon2/EffectNodes-for-cocos2dx
and i am looking for good 2d effect and tutorials. if you found any, please give me a link:), if i can understand it, i will try to implement it with cocos2dx.
