ok for well for that i have written py functions and given them to the 
numpy thing that eats them, 
http://docs.scipy.org/doc/numpy/reference/generated/numpy.fromfunction.html

a random one is numpy.random.rand(320, 200, 3)

like this i think makes some sort of stripes .. wrote that when was 
learning the system, am now not too sure if that makes sense but it does 
something succesfully, was just a test, .. but the actual ones am using 
in that thing are generated in the initialization of the app using that 
same function defining technique.

def grid_shape_colors(i, j, c):
   x = i % 2 #vert stripes
   y = j % 2 #horiz stripes
   np.logical_and(x, y).astype(float)

.. so passing an array defining function to the lib array generating 
thing like e.g. this:
change = np.fromfunction(grid_shape_colors, (GRIDSIZE[0], GRIDSIZE[1], 
3)) #i think i have 3 here 'cause it's rgb.
