Idea for a cool graphics demo

I've been really busy lately with all forms of HDRI and Advanced Lighting algorithms for my final year dissertation (far better than Muhammad's OS project [razz])

I doubt I'll find the time, but I was day-dreaming about a potentially very cool graphics demo/video. Probably more for the developer community though.

Over the decades of computer graphics a number of different material/lighting improvements have occured. It'd be pretty sweet to have some sort of rolling demo that showed this progression. Something like a FPS with the camera walking down a series of corridors through various rooms....

Start off with some really old-school basic lighting (e.g. ambient only) and slowly progress through to the latest-n-greatest.

Stage 1: Fixed Function style
Ambient -> Ambient + Textures -> Ambient + Diffuse + Textures -> Ambient + Diffuse + Specular + Textures

Stage 2: Early Programmable style
Per-Pixel/Programmable Blinn-Phong (bump mapping) -> Shadow Volumes (Doom 3 style)

Stage 3: Advanced Shaders
Shadow Mapping -> Soft Shadowing -> Advanced Lighting Models (As per previous journal posts) -> High Dynamic Range and Tonemapping

Not sure if SH/PRT can be combined in there, as it sort of runs in parallel and doesn't really replace anything.

Ack!
My OS is going to ownz0r your pwnz0rz!! It's going to have built-in MMOG support lol! And DirectX! And cool graphics! And all kinds of hardware support. And lol.

Sounds like a really cool idea indeed. Would have a great educational value for those new to the scene of graphics. However, you'll need a good map. Corridors don't cut it. Something like the original Unreal's 'Castle' that's shown behind the menu would be good. A castle with a moat, that is:
1) Complex architecture
2) Lots of lights, lots of shadows
3) Water

Even though it doesn't replace anything, it's still a recent development, so it definitely fits in to show how things proceeded.
