It's based on the implementation of LUA within SGE which I believe is very easy to use, so I hope that the people who read the tutorial think so too.
I also added a tutorial on texture management, previously, you could only get the demo with source code, so I threw together a short guide on how it works, and how to use it. You can find it in the same page as the LUA tutorial.
The demo for the LUA tutorial came out cooler than I expected, I noticed D3D9 came with some very nice sample artwork, so I borrowed it for this demo. After all, it IS a Direct3D 9 demo.
And now, I have to roll out the VOIP software... I hope it works "out of the box"...
