Does anyone have any links to simple demo applications written in openGL that demonstrate basic First Person Shooter principles and code. I am not asking for games, just little sample applications that are FPS based. For example, http://stevemooradian.com/programming/opengl-first-person-shooter is just the type of thing i am looking for because its nice and simple. (Also, we're using the same book which was very coincidental lol) I have checked http://www.opengl.org/products/platform/C5/ but the searching and filtering is a bit to wide of the mark and means i would have to go through hundreds of links to find anything useful. Thanks.

While learning to warm up to the FPU i wrote this one...

I have also made SSE2 hand-rolled matrix version.

Just a quick note. I used the CryEngine1 and although it is probably basic by todays standards it was a really easy engine to work on. I basically learnt Lua with it and the old community still has a few members active and there was a great programming Lua tip sheet that the community created. The menu system was the only item I had a problem with.
