I've written up a stripped down version of the code. I apologize for the bad
coding; I am in a bit of a hurry.
import random
import sys
import time
sizeX = 320
sizeY = 240
borderX = 20
borderY = 20
# generates a zero matrix
def generate_zero():
matrix = [[0 for y in range(sizeY)] for x in ra

The project I'm working on is motion detection, involving a bit of image
processing. No worries: no image processing background needed.
Suffice to say that I initially wrote a script that goes through every pixel
of a 320x240 picture (turned into an array using PIL) and performs some
calculatiosn.
