I want read the data from the screen, make it into a texture, and then use the texture in the scene. I could render small image for a security camera type thing like in Duke Nukem 3D or make an interesting mess like when you have two mirrors face each other. Or I could make screen shots. Anyway, how do I get the data from the screen?
Chess is played by three people. Two people play the game; the third provides moral support for the pawns. The object of the game is to kill your opponent by flinging captured pieces at his head. Since the only piece that can be killed is a pawn, the two armies agree to meet in a pawn-infested area (or even a pawn shop) and kill as many pawns as possible in the crossfire. If the game goes on for an hour, one player may legally attempt to gouge out the other player's eyes with his King.
