I got normal mapping working! Yay for me! :D
Why does the literature out there on such topics only work in certain scenarios!?!?! After fiddling around with subtleties in my normal mapping shaders I finally got it working... so here's per-pixel diffuse + specular lighting, where each pixel has a unique normal defined for it via a normal map.
It looks pretty cool spinning in real-time, so I'm working on a demo, watch this space.
On the left is per-pixel diffuse, on the right is normal mapping:

That looks pretty good. Where did you find the texture at? I've looked around a bit (I will admit half-arsed) for textures that include a good normal map, but haven't found anything as nice as that.

This specific texture came with ShaderDesigner from Typhoon Labs, but I also got a copy with my shader book "Shaders for Game Programmers and Artists".
The normal map I made with the program TGAtoDOT3.exe from ATI. As the name suggests give it any tga file and it'll spit out a normal map for you. It's free, and it's here:

The demo is uploaded here:

if anyone wants to try it on their hardware
Same deal as before, this is GLSL so you'll need to run it on Windows XP.
I noticed a small graphical glitch, so I'll look into that now.

Looks very nice! (I love shiny normal mapping, it just looks so sweet [smile])
One problem, though - I wanted to try out your demo (as well as the previous lighting demos), but you always provide an .msi [wink]. A zipped archive would be a lot easier such that we don't need to install anything just to try it out.

I think an installer file is about as easy as it gets: you download it, run it, and it puts everything in the right place. All you have to do is click the shortcut it makes for you. Removing the files after you've had your fun is just as simple.
I know some people don't like them so I can respect your decision not to try this out if that's what you want to do
