/*i'm so excited, i can't believe i actually got this workin this far.
i'm trying to recreate a sort of Tom Friedman effect - the trippy Total cereal boxes..
later i plan to implement a class (object?) called chunk 
that would have all the parameters like width, height,
and an array of pixels to hold the ind. pixels of each chunk, so i can try accesssing them
and do strange things with more flexibility...
yay! my first program!
