"A bunch of over-caffeinated white people..."

The post's title is one of the lines said in the film "Crash", more particularly by the big mouth Ludacris. And this is what I only have to say about the movie: You take a bunch of big names in Hollywood, squeeze them all in one almost-two-hour film, they won't be sharing much screen time, but their characters are all going to be interconnected, and you can now draw a diagram that can summarize the whole plot of the film. In engineering, it closely resembles an FSM state diagram.
