I've decided to learn OpenGL ES 2.0 for use on the Pyra. And as I started poking around I realised that there's not a lot of learning materials for the kind of stuff I want to do, and some of these things I'm learning might be useful to others.

So I'm writing a blog documenting my journey. There's very little in it at the minute, and I imagine it's going to be a long time before it's complete. But on the off chance that it's useful to anyone, feel free to follow along :

Intro :
