Well, dealextreme has a bunch of webcams, that can give decent video in mjpeg. (Apart from those that are actually crappy). However or this purpose it's better to use some analog cams.
There are 'security analog camera 380tvl' therre for abou 10$ and give a better picture at a better framerate. And there are analog devices chips that will deliver you digital yuv signal. Good luck, really want to see your build.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
