iNGL is a port of the main NCCA graphics Library ngl it is a completly seprate branch of the code designed to work with OpenGL ES2.0 iOS 5 devices (such as the iPad / iPhone 3GS and above).
This is very much work in progress, and I will attempt to create more demos / tutorials once I get some time. You can download the main library using bzr here

At present there is very little documentation but more will be added soon once I get a change, If you do use this please let me know, any feedback and comments are welcome.
